Do Nails or Screws Have the Most Holding Strength (not shear strength)? Let's find out!

The difference in holding strength or pull-out strength (lateral load or shear strength not tested) among different types of nails and screws is amazing! The type of coating used on nails and screws makes a huge difference. In the video, 5 types of nails and 2 types of screws get tested for tensile strength in untreated 2x4s. Each type of fastener is tested 7 times and the highest and lowest strengths for each fastener is "thrown out". The types of nails include 16D coated, uncoated, galvanized, spiral shank, and ring shank. The types of screws include 3.5 inch drywall and coated deck screws. Shear strength is not tested in this video, only pull-out or holding strength. Highly recommend following applicable building and construction codes when building structures. Drywall screws provide tremendous clamp load but aren't designed for structural connections.

[@unclemikeb]

Amazing job on this test. You helped me feel better about the investment I made in a 10 x 20 shed. I wanted it to hold together in case we got a strong west wind. So even though code didn't require it, I built it on 16 inch centers and I used torx screws all around. That allowed me to build it without a lot of pounding and the screws really locked that thing together tight. I had a really useful tool my son bought me. It is a battery powered drill with a removable chuck. When you remove the quick release chuck there is a 1/4 inch hex under there that can hold a short tool tip. I put a short #25 torx in there so I could use just one tool. Where I had to fasten at an angle, I would drill a pilot hole, remove the chuck, and then run the screw in with the torx tip. It worked very well for that type application. The chuck fit in my tool pouch when not needed. Seeing your demonstration helped me justify the extra cost of the screws. I chose the torx because I have had too many phillips strip out, so it is only torx for me from now on.

You should probably note nails are primarily used for SHEAR (lateral force) strength and screws are for COMPRESSIVE (holding) strength. With lateral loads like framing weight, you use nails. For mounting drywall or decking, you use screws.

And equally, most nails should be hammered at an angle on framing to have the attached piece naturally get pulled inward by the forces exerted on it based on the angle of the nails entry

[@natashagk7877]

I agree and was going to say something if someone hadn't. I was removing spiral nails from pallets for repurposing and holy mother of pearl those things are beasts.

[@CJBanks-nc5re]

I agree that the spiral galvanized nail would have held much better if the pulling jig had not been allowed to twist. I also agree that when framing with 16d cement coated sinkers that are 3 and 1/2 inches long and when you drive them fully through to attach one 2x? to another you would have a full 2 inches embedded into the receiving 2x?, or as you stated they would be driven at an angle to maximize their holding strength. Another point to take into consideration is the grain structure of the wood the nail is being driven into that would greatly affect its holding strength.

[@johnperkins630]

look at load calculations. This is what he does not do. Beams can not be built with screws because of shear strength. Bend a screw over and it breaks. Nails bend and have to be bent back and forth several times before even thinking about breaking. Screws have great power in one direction and zero strength in the other. Nail have strength in both. Beams built with screws will fail and no insurance in the work would pay for it. I am a contractor and have to deal with load calculations daily. screws have thier place but you can not say they are better than nails. Each has their place and function in which they exceed expectations. I could redo these tests with variations and make it so you never want to use screws again. He needs to get his facts straight before causing someone to use the wrong tool for the job.

[@digitalgulby]

This is a neat test, but as someone who worked in the collated power fastening business for several years I think there is something worth noting. I worked for SENCO, and sold lots of collated fastening products including nails and screws. I think it's worth stating that while screws have incredible holding power, there is a reason they are not used for framing. Drywall screws do NOT do well in event of catastrophic failure such as storm damage or violent lateral twist (shearing). You should not build a house or anything structural with drywall screws, they will snap very quickly if any lateral force is applied to the beams. Yes, they do make screws that are designed for framing but you should NOT substitute drywall or general purpose screws for a real framing nail. Great channel by the way, fun stuff. LOL - looks like others commented same as I did.. Shear value, important to note!

As a hardware store employee and formerly lumber yard sales guy, the galvanized nails are likely common nails. These are thicker than the same named size in coated sinkers; sinkers are also slightly shorter than their name in pennies.

[@ronmason4306]

Very good video! I felt the spiral shank may do much better in a real life use situation. The single nail was allowed to spin in the test. I feel like the pulling force of two boards nailed together with a spiral shank would be much greater since the first board would keep the nail from spinning. Pulling a spiral straight from the wood without it turning seems like a very strong nail. Any thoughts?

[@mikeappleby5687]

Why would the upper board stop the nail from spinning? The nail was driven through that board the same as it was into the lower board. Both have a spiral path carved through them, and the nail will follow that spiral path on its way out.

[@andreasbingkilvr6662]

​@@mikeappleby5687"The upper board" would not spin because you would put at least 2 nails in it, unlike in this test, where one can clearly see the upper part of the testing-apparatus twisting the singel nail out, along with it's pulling power. For a better testing methodology (for that spiral nail specifically) it would be better to have something block the twisting motion on that puller. Maybe som vertical bars, stopping the lateral motion.

[@francisR46]

Great video as usual. Thank you! One thing I noticed. The galvanized spiral shank test. The jig turned allowing the nail to "unscrew" itself from the wood. I believe if the screws had been pulled straight up without the jig and the nail rotating the nail would have had a lot more holding power. One of the reasons they hold better is because as they are pounded in they act almost like a screw, twisting into the wood. Having tried to remove those type of nails from deck boards I know they hold better than a smooth shank nail. They are a pain to pull out.

@@denisl2760: "but it did get a little repetitive. Would've been better to show just one example of each, and then a chart at the end showing the data" Fair point, but I actually enjoyed seeing each one. For me, it made the whole test more believable. I don't doubt Project Farm in the least, and the reason for that is due to the degree of effort put forth in his testing. If the results charts were shown right after an example, then followed by the actual footage, I would still have watched the entire video. It really give me that satisfaction that the test is complete as stated. Otherwise, I have to interrupt what is in the chart with a little more effort. Hearing a description of the results while showing a chart still does not compare to seeing the entire thing. Also, consider that an example followed by the chart would be harder to understand for non-English speaking viewers, and the same for those that have hearing problems. Project Farm always makes videos that cover a decent spread of products that are being tested, rather than leaving out a whole lot of them. Still due to the variety of products, there will be some good suggestions of others that could have been tested. All good points. Also notice that each segment was edited to show just the meat of the test. Things go swiftly but with the visual aid of showing it, everything is easy to understand. There is never any wasted "fluff" in the videos. I wish more KZbin testing videos by others were as fine tuned. As you can see from the comments, there have been several suggestions of how the tests could have been done differently. None of those imply Project Farm is not trustworthy either, but they do show that a different type of test could have been made. Seeing the video of each test the way it was performed gives me that satisfaction of understanding exactly what was done. For example, seeing the screws tearing up wood when removed adds to understanding what is happening. A chart could never do the same in these instances. I don't disagree with you, and I think a lot of people might even prefer your shortened method, but for some of us (at least me), I am completely satisfied with how it was done. If a shortened method is preferred by the majority, it will surely be reflected in the comments.

I was told drywall screws are designed to snap off so that if they won't go in fully because they hit something, they will snap off and not damage the drywall.

[@stevelovesgod]

thats because screws are made of hard metal and nails of soft metal... So hard metals have much higher strength, but it breaks when it fails. Where as Soft metal will Bend. Think of a Cast Iron Pan vs a Spoon as far as types of metal.

Pre-drilling actually increases the surface holding area, unless the screw is self-tapping the wood fibers will split apart and there'll only be the grain in one direction touching the screw. Deck screws should have a notch in the end to make them easier to screw in, so drilling is pointless.

I always remember galvanized having a rough matte finish... which likely contributed to their holding power

[@Shadow_Hawk_Streaming]

Almost certainly,same for the coating probably

[@fearlesscrusader]

@@Shadow_Hawk_Streaming There are two methods of making galvanized nails (and screws). Th e better way is "hot dipped", in which the nails were actually dipped in molten zinc. They were extremely rough and covered with warts, which did contributed greatly to their holding power. Nowadays it's hard to find anything but "electro-galvanized", which is merely a thin smooth coating (not unlike the "smooth candy coating" on M&M Peanuts) with relatively little holding power. I'd like to see him compare the two types.

Ooo, so sorry, your pulling of the spiral shank, ardox, they need to be tested without the twist being allowed to unwind. they do offer HUGE resistance when not allowed to unwind.

[@hotfudgemoney]

The people saying that the nails are going to be allowed to unwind in a real world scenario don't know how to frame a deck.

[@thedevilinthecircuit1414]

Spot on. The spiral nail's holding power is achieved when it is driven through two thicknesses of wood. The spiral prevents the two pieces of wood from separating. If you've ever demo'd a deck or dock assembled with these, you'll know their joins are almost as difficult as screws to pry apart.

[@buzzbbird]

@@hotfudgemoney correct. I hope you understood that i was saying the TEST was without value in measuring holding power because it was twisting when coming out. In real world use, ardox nails are a bugger to pull out because they do not unwind.

[@betsypwnsyou]

Agreed I have just recently pulled some from a deck and they have some serious holding strength

[@therising1]

I understand the physical property you are talking about, but is the pull force much greater than the galvanized nail? How much MORE force could be used? As he said in the video, used in a hardwood (as they're designed for) they'd probably take much more force. Very interested in the pull force required in a test with two pieces of wood!

[@jamestaylor5995]

Great video. I learned a lot from it. I've done professional remodeling for over twenty years, and 2 1/2" star drive deck screws have become my go-to for just about everything. I can use them indoors or outdoors, and in decks to everything else. The best part about the star drive is the heads don't strip under heavy load. And they're perfect for temporary holds were you want to take things apart again. Their versatility makes them worth every penny. When I need a shorter screw, I still use drywall screws that are 1 5/8". They're cheap and short enough the heads don't strip out under load. And on small projects they have better holding power than nails. For those occasions where a hammer driven 16 (or 8) penny nail is called for, I keep coated sinkers on hand. I've always had better success with them than common nails. Finally, I still use my nail gun for basic framing projects. It's cheaper and faster than screws and they work.

[@ProjectFarm]

Great tips! Thank you!

[@jttech44]

@@ProjectFarm It'd be cool to test the spax screws in a followup video. They're a little pricer than drywall, but the self drilling and the hold seem to be top notch, and they're cheaper than those fancy "decking" screws, at least around my neck of the woods. Also probably worth mentioning that the 'decking' screws you showed are way, way overkill for decking.

@Dave Gill I said I use nails where applicable. Why ignore what I said? For many jobs the shear strength of screws is sufficient and their holding strength is the primary importance. I'm sure one can misuse star drive screws. But where I've used them, I've never had one subsequently shear off.

[@ProjectFarm]

Thanks so much! Thanks for the video idea.

[@802Garage]

First, fantastic video as always. I'm extremely surprised how much difference the coatings made on the nails. Watching the spiral nail segment, it made me think it might be a more accurate test to actually have the fasteners secure two pieces of wood together. Two 2X4 boards in a cross shape for example. Then test the force to pull the pieces of wood apart. That way the spiral nail couldn't rotate as easily. I don't think you need to retest or anything, as it would mostly affect spiral nail. It would also be interesting to see all the fasteners tested on harder and pressure treated wood, though obviously many are not meant for it. Standard wood screws, aluminum nails, stainless nails, and silicon bronze fasteners would all be interesting to see tested. I'm sure there is basically an endless amount of hardware you could test though. I definitely feel more informed after watching. Plus, as usual, I ended up researching related topics for a while because of the video. Thanks a lot!

Todd, Your tests could literally save lives & property. If I lived in Tornado Alley or Hurricane prone coastal USA, forget nails. I would use Deck Screws every 4 inches on roof sheathing AND your best tested, Project Farm construction adhesive along with code required rafter ties,etc. Once violent winds rip off one sheet of plywood roof sheathing and allow storm driven rains to enter, lives and the entire structure is often lost for the cost of fasteners. I remember one issue of FINE HOMEBUILDING where architects went down to Homestead, FL post Hurricane Andrew to learn about Hurricane damage mitigation by analyzing destroyed houses. The Hip Roof survived much better than traditional Gable and other roof designs. Naturally, there is now strict Hurricane compliant building standards in place in many FL counties.

[@G_Cs]

@Derek Stairs: >"Phillips ..., I don't know how they ever became a thing" Because P.L.Robertson (Canadian) refused to license the design to Henry Ford (U.S.). Mr. Ford had already discovered a time savings in production, but when Robertson declined the licensing, Ford went ahead with Phillips screws, which made them immensely popular, in spite of them not being what he wanted. In fairness to Mr. Robertson, he supposedly had just went through a significant issue with licensing the design to an English company, when the owner caused the company to fail, so he could purchase the rights they had at a reduced price, avoiding the initial license agreement. Robertson spent a small bundle to get the rights back in this total control. You can imagine his concern with licensing to Henry Ford, who already had a reputation of doing some shady business practices himself.

[@jonallen5280]

Great test and very helpful, but two things to consider. 1) There looked to be a noticeable difference between the holding power of the nails based on how straight or angled they were in the wood. Nails with a straighter entry seemed to hold less compared to the same product at an angle. 2) The Ring Shank nail was at a great disadvantage because it was allowed to spin right out of the hole. If you attached two pieces of wood together and tried to pull them apart, they would not allow that to happen. I would imagine they would perform better than the straight nails, if they were fixed.
