Thread Anatomy- (In less than 5 min!)

A 3D animated video showing the anatomy of threads. Machining threads is difficult enough so its time to start with the basics. Watch this video to learn the basic anatomy of threads.
From Metric threads to standard Imperial, lets dig into what kind of threads are out there. We will answer this with a quick definition and general use of each individual thread. This is just the "Tip of the iceberg" but we all have to start somewhere! By the end of this video you will be able to identify and describe the following threads: Metric threads, Inch threads, Acme threads, Knuckle threads, Modified square threads, Sharp V threads, Buttress threads, Worm threads and of course Whitworth threads as well. Enjoy and Ill get started on the next video!

Excellent video. I've spent almost thirty years operating manual lathes, and have cut many different types of threads. There's one thread type that I've cut that you don't mention: Trapezoidal thread, similar to Acme, but with all metric dimensions. Note to newbies: The differences between thread types are pretty obvious when they are drawn on paper or computer graphics, but not always so obvious when you are looking at a machine part, especially if it is worn. Trivia: If you ever encounter an oddball thread that mixes an imperial diameter with a metric pitch, or vice versa, it was probably made in Italy. (It ain't stupid if it works...)

[@countrymule9623]

I never had to cut Trapezzoidal threads. We would puchase RH and LH threaded rods and machine the ends to our customers print.

Thank you for the information! Such content I've never had before. Now I know why screws are often so different.

[@pl-mn2ro]

Here after are some additional information about Metric system To find the drill size for hole that will be taped you just subtract the thread pitch. Exemple: M8 x 1.25 tap would need a 6.75 mm drill bit (8-1.25= 6.75) Also every screw or nut revolution will make it progress 1.25mm Also for small metric size you can find the wrench size you need by multiply the pitch by 10 Exemple: M3 x 0.5 would be a 5mm wrench (0.5 x 10 = 5 ) and 2.5mm drill size M4 x 0.7 would be a 7mm wrench and 3.3mm drill size M5 x 0.8 would be a 8 mm wrench and 4.2mm drill size M6 x 1.0 would be a 10mm wrench and 5mm drill size M8 x 1.25 would be a 13mm wrench

[@alan-sk7ky]

Its all so... logical and purposefully done, oh that Si ;-)

[@robertstout4764]

Re: "you can find the wrench size you need by multiply the pitch by 10" That's not exactly true... It usually works but, for example, a M8 x 1.2 bolt or nut made to the old J.I.S (Japanese Industrial Standard) will use a 12mm wrench not a 13mm wrench. A lot of the JIS standards were changed in 1985 to match the ISO and DIN standards but I don't remember if this is one of them.

I've never seen metric drills on consumer market in US. Always fractional inch, decimal inch, wire size or letter size. I'm pretty sure I saw a few metric drills here and there working at Caterpillar, but mostly I recall decimal inch even though the prints were all metric. I've also seen odd hex sizes like 16mm hex on a 10mm bolt, 14 or 12 on an 8mm bolt, and that's not the special reduced size hex for clearance. Also 18 or 19 hex on a 12mm bolt. Mostly I see the odd hex sizes on Chinese stuff, but I've seen the 16mm head on 10mm Cat bolts with "CAT" logo on the head (not cheap China stuff).

Great video! My first Machinery Handbook I purchased was used. Was the 20th edition 4th issue printed in 1978 and I've still have it. Long before we had Cad system in the shop along with all kinds of new tech that was amazing to us old timers. Cleveland MoMax cobalt was the good stuff back then. Finally convinced the owner to puchase carbide inserts. He was blown away by the time we saved him. Now you talk about a old school machinist he was the OG.

[@jimf671]

The WHITWORTH thread of huge historical significance because it marked the introduction of standard thread forms by Joseph Whitworth. Although most people take standard threadforms and other manufacturing standardisation for granted, Whitworth's standard thread and his other standardisation ideas brought a massive step forward in manufacturing efficiency from which we still benefit hugely today. Although fallen from use for general engineering, most KZbinrs, and many other people, use Whitworth threads every day since 1/4" Whitworth is used for the tripod mounting thread on most still and small video cameras and 3/8" Whitworth on large video cameras. The Whitworth thread form is used for British Standard Pipe (BSP) threads, now renamed ISO R and ISO G.

[@DaveEtchells]

That’s fascinating, I’ve been a photo hobbyist for 50+ years, and always assumed that tripod threads were just SAE. A standard 1/4-20 bolt mates fine with the standard camera socket. I kind of wonder why they didn’t just make them SAE at some point, are there some situations where they wouldn’t mate, or do they only mate due to over-generous tolerances?

[@jimf671]

These fasteners are intended for items that are finger tight and they need to be very easy to align and engage by unskilled users. For those reasons, the tolerance band can be large since a finely fitted high strength thread is not required. That wide tolerance band means that on most occasions both the 1/4 and 3/8 versions fit together regardless of which standard is used. However, since the Whitworth will have a deeper thread because of its narrower angle there can be interference. Probably more likely when fitting UNC screw into a Whitworth hole. A good reason to be extremely careful when mounting expensive, particularly classic, cameras onto low-cost mounts made recently in workshops of unknown origin. Personally, I feel it is worth pressing home the point about Whitworth for cameras because it is just so cool keeping that important piece of 180 year old engineering history alive in every camera body and mount.

[@rixretros]

Excellent vid with great animaton. One caveat for the newbies out there. Mass produced capscrews/bolts and nuts have ROLLED threads which have zero stress points at the rounded root and crest. This makes them stronger than MACHINED threads which have sharp edges at the root and crest. These sharp edges are stress prone and thus make machined capscrews/bolts and nuts weaker. ALWAYS use fasteners with rolled threads whenever possible, especially in high load and/or vibration prone areas.

[@Whatda25]

Awesome. Simple and clear!

[@Thestargazer56]

Thank you for the very informative video. I used to wonder why there was no single standard pitch and TPI for screws (AKA bolts, nuts augers, etc.).

Just found your channel, great video! I'm not a machinist, but sometimes do make things for my personal use! Love the video clears up a lot for me! I do airbrushing (as a hobby, I'm retired!) and I have an Iwata Vault Th2 (it's larger than normal airbrush) that has a screw-on paint cup! Iwata is Japanese made and it's a great spraygun/brush with a round and flat spray pattern that I use for mostly clearing my finished paintings. I wanted to get a 3M PPS 2.0 adapter for it so I could use the 3 oz. paint cups on it to save a little $ by putting the cap on the plastic cup when I finished or if I'd like to give a coat the next day and not waste the clear I already have mixed! It's about a 2 day pot life once the paint is mixed if sealed! I want to be able to clean my gun but save the paint, which the 3M cup would allow me to do. But the thread is not a normal thread. I have a thread gauge in metric and it's almost a 8 mm 1.5 thread, but although it will start, it binds after about one (gentle) turn? I have contacted the company and they say it's proprietary information and will not give me the thread nor do they make a 3m adapter that will work. I guess my question is, any idea what I'm dealing with, or if I go to a local machine shop will they be able to tell me what thread it is and be able to modify a 3M adapter with a little larger thread to fit it? The closest machine shop is quite a drive away from this ole country boy and I'd like not to waste a trip in these days of expensive gas! LOL Thanks again for a great video and any info you could provide would be appreciated!

[@bradjohnson9671]

I just did a search for Iwata to 3M adapters, lots of different ones available, I didn't find one specifically for the Vault TH2 but I'll bet there is one out there. This is he search I used "Iwata air brush cup adapter to 3M"

[@billybubba600]

@@bradjohnson9671 I have searched all of them, believe me! 3M makes one for the Iwata LPH80 and their are side feed adapters for other spray guns which has a spin-on type mount but none for the Vault TH2. Iwata only made the Vault version of the TH2 for a limited edition and I was lucky enough to buy one during that time. Got it from a on-line beauty shop, LOL. But the TH2 is almost the same. Mine has a black handle and it's a little thicker handle than the TH2. But the cups are the same. Creos also makes a gun that's like the TH2 and those cups will screw on too. Iwata and Creos are sort of like the old Sears Kenmores being made in Maytag plants and a lot of the parts would interchange. I know because I have bought Creos cups to take with me to the machine shop when I go to have an adapter modified. If I knew what thread it was, I might be able to buy a die with that thread and I might be able to use my little lathe to turn it down and them use the die to thread it. But I'm no machinist, wish I was. So believe me when I say that I've tried everything I can think of. I have bought several taps that are odd size metric since my thread gauge didn't have a thread that size, but no luck finding the thread. I think it might be a JIS thread and I may buy a couple of pieces of hardware with those threads just to try them. a link to JIS threads -- www.malonespecialtyinc.com/product-category/jis-fittings-japanese-industrial-standard-fittings/jic-thread-specifications/

[@billybubba600]

@@bradjohnson9671 Createx (the airbrush paint I use) has a channel and I saw Chris Alpin using a TH2 with a 3M cup on it and I contacted Chris about how they got the 3M to fit on their TH2. Chris said they just cut the plastic and slid the cup over the existing cup. But that doesn't solve my problem. I want to clean the gun leaving the unused paint in the cup which has a plastic cap that slips on the bottom of the 3M cup. The way they did it the cap will no longer fit on the cup as you have to 'cut' the bottom of the plastic 3M cup to make it fit. That means that the cup is not 'sealed' and leaves me with a metal cup that is still 'dirty' with a open hole in the metal cup.. My Vault TH2 is very expensive and I do not want paint hardening in it, plus I would like to be able to mix 3 oz. batches when I have larger projects. This has been a frustrating 'small' thing. But wasting a half cup of Createx UVLS clear, or mixing half a cup and finding out I don't have quite enough clear mixed to complete the project is costly and can result in ruining a painting as the clear needs to be applied before 'full' cure and since I paint on card stock, sanding it is very 'risky' procedure on paper, and I can ruin a painting that way as well. Some paintings take me days or even weeks to complete. I guess I'll have to go to a machine shop and talk with the machinist to see if they will be able to help me.

[@josephstratti52]

If you can find a thread cutter to match the Japanese thread screw the bastard 3m out to the Japanese thread.

[@chazmakarowski5429]

Your thread is a 5/16 diameter x 18 TPI most likely. 8mm x 1.5 = 0.3149 diameter x 0.0590 pitch 5/16 x 18 = 0.3125 diameter x 0.0555 pitch The difference in pitch isn't much but it would allow you to thread 1 or maybe two threads before binding. The difference in diameters doesn't matter seeing as they're so close to each other.
