Time Sert vs. Heli Coil | Best Damaged Thread Repair | Best Thread Inserts | Partzilla.com

[@NaberAuto]

Good Video. When working on a race car pit crew years ago, we Heli-Coiled all of the critical holes that we could and they never failed. We even Heli-Coiled the lug nuts because we had several times where they would get cross threaded before we Heli-Coiled them. I think the threads were getting worn even though we used Anti-Seize every time the nuts were removed. We never had to replace a Heli-Coiled lug nut despite going on and off hundreds of times and they never cross-threaded. Likewise, with the other Heli-Coils, we installed in the engine and other critical areas - they NEVER had to be replaced and we never had the threads pull out. Heli-coils with hardened stainless steel threads are far stronger than aluminum or cast iron. We've used thousands of them in the past 45 years in business. If you watch how loose the Time Sert was when being installed into the hole, it likely would have failed an official thread test. It is strongly recommended to use oil whenever drilling or taping metals. Otherwise, you get holes and threads cut oversize - and lose a lot of strength. Of course you want to degrease the outside of the Time Sert as well as the hole when planning to use Locktite to retain the TIme Sert. With Helicoils, you never have to use Locktite because the spring pressure prevents them from moving and we always used oil to install the Heli-coils. Both are great products - especially with aluminum blocks, heads and so many other parts. The Time Serts work well on plastic too (such as intake manifolds, etc). We use a soap solution for lubrication when installing either Time Serts or Heli-Coils in plastic parts to maintain hole and thread size within specifications.

Hello. Quality top notch answer there, one can really tell you know stuff. A question: In the first half of your answer it sounds like you think helicoils are best. But at the bottom you write both are great products. - Could you please tell in which situations Helicoils are best? - And in which situations TimeCerts are best? :-) Thanks a lot NaberAuto! :-)

[@jkg6211]

AWESOME... but did you see what happens after a year or more in a corrosive environment, like say, on an outboard that runs saltwater? It's a TOTALLY different ballgame.

[@falsedragon33]

Project Farm tested these. The TimeSert expands against the case when the bolt is inserted. It was able to take significant more force than the Heli-Coil.

[@user-ld6wo4rv8h]

@@falsedragon33 Both the HeliCoil and Timesert exceeded the strength of the bolt so it's mostly irrelevant that the Timesert could take more lengthwise force.

[@DonziGT230]

Heli-coils are not a 'one time use' or 'emergency repair only'. I've used them many times.

[@iFixJunk]

Gave this a "LIKE" simply because he listed the options as "A" and "TWO". Been doing this since my wife and I met. She only noticed recently. Now it drives her nuts.

[@jjse79]

Huh 🤔

[@jamese1596]

Thanks for the video. Just an FYI, Time Sert’s instructions stress that you want to avoid bottoming out the insertion tool. So only run the tool through the Time Sert until it gets easy to turn, which means the bottom threads have expanded and locked the insert into the hole. No need to go any further.

[@steveiname]

And a tap wrench

[@nck3500]

Your advice is requested: Aircraft. About 1/32" thick cover over an inspection hole in material also about 1/32" thick. Holding the cover in place, overhead, not level and inaccessible are (48) #10 size, 10-32 thread nuts that are riveted in place. The threads on the nuts are all stripped and oversize non-aircraft, 1/4 -20 machine screws go in, but not easily. Goal is to replace the non aircraft 1/4-20 Home Depot sourced machine screws with #10, aircraft machine screws, 10-32 thread. The 48 machine screws need to be removed monthly so the cover can be taken off for inspections, and then the cover has to be re- installed. There is so much drag that the 1/4-20's from HD have to be replaced every other time or they "cam-out". Not that much torque, just hand tighten with PH2. *AMS 10 machine screw and nut is one of the aircraft industry's description for the hardware.

[@grabir01]

Heli Coil was invented and used in air craft engines. Was much stronger than the original threads. To say it is a temp fix is not true. Heli Coil is a proven technology. Also, your first hole you drilled was crooked.

[@n7narcosis]

It's partzilla, they WANT you to spend more money. That's why they always recommend the most expensive option.

[@Mattschindig]

A temp fix for a bolt that will be removed from time to time. If you don't want to have to redo the thread repair the next time or two then Time Sert is the best way to go. If you aren't going to be removing that bolt for a long time if ever then Heli Coil. First hole could have been crooked, could have been camera, but it is irrelevant because this is for demonstrating purposes only as why would he put a Heli Coil and Time Sert on the same bolt pattern for the cover? If it was going to be used? He clearly states that he would use Time Sert. If you want to bitch it should be directed to Partzilla's new website navigation. Not Johns fault btw.

[@johnwick5901]

They use something called “speed tape” which is basically a glorified duct tape in air craft engine repair too. Doesn’t mean it’s permanent smh

[@Rick_Cavallaro]

​@@Mattschindig >> A temp fix for a bolt that will be removed from time to time. I've used helicoils for 40 years. Never had one fail. I currently use some on my kitesurfing equipment in a critical application. I get about 100 days/year on the water (saltwater), and I remove the bolts every single session to put the gear in my car.

[@Rick_Cavallaro]

But to be fair, I never drill and tap the hole blindfolded like he did.

[@mikeadkins8215]

I'm sold on time-serts for their ability to handle a lot of torque. I repaired 7/16 inch mounting holes for a 62 Fairlane strut bracket, using fine threads to increase torquing power. They are costly and a blind hole sometimes doesn't offer enough room to run the insert tool deep enough to flare out the insert. Heli coils are fine in low torque applications. I used them to repair the carb stud holes on my vintage edelbrock intake, and they are just fine. And far less expensive.

[@andyt1462]

Using a tap wrench instead of a spanner gives much better control and helps to keep the tap straight. Clamping the casing so it doesnt spin is aslo a good idea for several reasons and don't forget your safety glasses especially using compressed air to eject the cuttings🤕 All being said great video to show the comparisons. Thank you

[@Stu-SB]

Tap wrench is a good idea, I'm just about to do a snapped nipple on an RS4 caliper..

[@matthewtaylor5290]

I cringed when the spanner came out 😄

[@kevinhancock4064]

But I don't think heli has moved I dud at 1st I'll inspect once I get cylinder back off . And stud out (bolt I mean) just don't get how it's broken before torquing up

[@515moto]

Great video - In shop class we were always taught to use cutting oil / motor oil whenever drilling or cutting threads. WD40 is a good cutting oil as well

[@xESPplayer500x]

Cutting oil is the exact opposite of engine oil look into it. They taught you wrong. Cutting oil mates surfaces engine oil seprates them.

[@sciglassblower]

Heli is great! If you can't drill or tap straight, why would I take your opinion?

[@chrish.6629]

The hole is crooked, the thread is cut crooked and I would have used an attachment that can be held centered and not an open-end wrench. A good example of how a beginner can ruin everything. The drill hole should also have been countersunk at the top. At least that's what the manufacturer of Helicoil says. With Time-Sert, however, you should use a special milling cutter. It is part of many Time-Sert Kits. Actually, everything was done wrong here. Atleast not to the manufacturers specifications.

[@nobodytonobodysbusiness]

Timesert is right. Good advice.

[@grosbeakmc]

Very helpful video! Presumably if you were doing this "for reals" you'd want to use (a) a drill press, stepping up the drill bit sizes, (b) a tap handle to guide the tap (maybe (c) a tap follower too since you've got the drill press), (d) cutting fluid, and (e) compressed air to blow out the swarf and the broken tab of the helicoil.

[@keithkrueger1609]

as a tool maker we use helicoil in our alum molds and plates that get changed out almost daily. they have seen 1000's of cycles of bolts in and out without failure. also why tap with the small wrench when you had a tap handle handy. i would avoid your shop after seeing this video. all this video showed is you make more commission from time serts

[@rivit7615]

Exactly. This was a shil for Timeserts. Had to be. Either that or this guy hasn't been turning wrenches for very long. Heli is a temp fix LOL!

[@grimsgrave6327]

I’m trying to repair the thread on my timing belt tensioner on my 2jz engine, I’ve repaired or have made threads. The threads I’m trying to fix are 10mm x 1.25 so do i have to look for a tap and dye set in that size or one size bigger like a 10mm x 1.5? Or does the 10mm by 1.25 kit already compensate for the thread insert?

[@6226superhurricane]

you don't need a punch to break the tang you just remove the installation tool turn it 90 degrees, push down and break the tang then remove it from the hole. helicoils can be used indefinitely they are not one time use only. they are also stronger than time serts and take more torque to yield.

[@ronaldmontgomery8446]

I have used a keen sert with the small keys that you drive in locking the insert permeant.

[@Coodeville]

I had a thread repaired in a 500 Caddy intake manifold. It holds a bolt that secures the compressor but also blocks off vacuum as well as it goes through the intake runner. Bad design in my opinion. The machinist went with the Time Sert because of the durability.

Well never heard of a time sert. Been using heil coils for years. But I would like to see a cost comparison. Heli coils have got ubber expensive like everything else. I have a few kits I've paid in excess of $75.00 each, to fix one hole. But that expense was also I needed it right now rather than waiting a week or 2 for an online order. I have heli coiled head threads with no problems. Sometimes I drill out the alcoa and put in heli coils simply because over time the metal to alcoa monster growls and threads pull. And yes brake clean and red loc tite.

[@kcretired1032]

So is the Time Sert Threaded all the way onto the Driver Tool before you thread it into the newly tapped hole? Or is the Driver tool only partially threaded into Time Sert when you start to thread it?

[@LastCall534]

It doesn't matter, because as you screw the time sert in with the tool. It will thread itself all the way down into the time sert and spread the bottom, locking the time sert into place. Hope that helps.

[@AngliaNutz]

A Heli-Coil will last just as long as a Time-Sert. I had Heli-Coils in every head bolt hole in the aluminum engine block in my dragster and I never had one fail. They should use a person with the aptitude to demonstrate things like thread repair. Using a thread taps without oil or another cutting compound is very armature. Also a person that can hold the drill motor perpendicular to the work piece. That countersink sucked big time.

[@RedRupert64]

I've been using Heli Coils for many years. Never had a failure - they will last. Occasionally I use Heli Coils before a thread fails when that fixing is likely to be used time and time again.

[@joshscott8678]

Would JB weld work with time sert , i know theres more mass but wouldn't the excess be able to get threaded

[@stevdbird3424]

Nice bit of dovetail bolting.

[@NaberAuto]

Great video.... A huge help is to drill out the threads in steps with oil on the drill, and the drill will follow the hole, and maintain the correct hole size much better than going in with just 1 drill.

[@Jonodrew1286]

There are always pros and cons - helicoils are good if the hole has good clearance but not too much and if installed properly - people always forget to drill out all the parent thread - and this can jack out the helicoil - they can skip threads if you dont pull slightly against them when carry out its installation- helicoils are prices well and robust - the cons are if the thread has hole has too much clearance the helicoil will not fix that - Time certs - industry standard / expensive - can fix a hole with larger clearance but a deep hole can present problems if there is no suitable counter bore to sop against and drilling a counter hole at the top to make it flush can also be problematic if there is an oil or water groove close by or the wall thickness is not there - so pros and cons one is no better than the other - its just that industry has leaned towards a solid insert rather than a coil - but that does not make it a better product…..!

[@roots4x]

Assuming none of those Time Sert cons are applicable, and that will be for a LOT of people at home working on their cars, Timesert is more durable and can handle far more torque. That's why it's approved by OEMs to repair engine blocks. It works in almost all cases and can be considered a permanent fix. Definitely not for the Helicoil. Cost? What will it cost you to replace an engine block because you used a Helicoil?

[@Jonodrew1286]

@@roots4x I am inclined to disagree, just because the industry has leaned towards a particular brand - an insert of any type is only as strong as the material around it - a hole or the right pitch and clearance is necessary - I have seen time-certs fail on BMW M52 & M54 as overheating actually sinks the material between the liners and the aluminium alloy actually softens when going past a certain operating temperature (overheating) I have been doing automotive engineering for 25 years and have been using helicoils for just as long - If not installed properly they will pull especially fine pitched threads- Time Certs / WÜRTH have just priced them selves exorbitantly - Horses For Corses

[@davidnielson5252]

If you go view several YT videos where they test torque to failure, the time certs did not do as well as the helicoil. The helicoil outlasted a grade 8 bolt...over 8,000psi. Helicoil is solid if installed properly.

A gearbox thread is a tapered thread. Heli-coils are straight threads so you can't use them.

[@andyt1462]

The tool for inserting the helicoil is used to remove the tang. Just twist in opposite direction. It naturally locks in place as unscrewing it expands it. It can't go anywhere. By using punch you run the risk of dislodging the bottom thread or two of the coil insert. JS 😜

[@kevinhancock4064]

Why is it that most say to hit the tang off once installed ? I thought that was how they work ? Would not allow the stud/bolt to pass it if needed ?

Great video mate 👍 I'd advise anyone with access to a drill press to use that instead of a cordless drill. It looked like it wasn't completely square due to this method.

[@iFixJunk]

Agreed, and I observed the same in the video. Unfortunately, a lot of the times I've had to do this the part was not something I could bring to the drill press (like a mount on the side of the motor), so I do my best to start slowly so I can see if the bit is cutting more on one side; then I adjust accordingly until my drill bit appears to shed chips equally on the entire perimeter of the hole. If possible, maybe use a jig made on the drill press that you can bring to the engine, if necessary, but I've always had to just wing it.

[@kevingoon2747]

Why did he drill first and not just Tapp and insert

[@philippe94416]

Because that's the correct procedure for helicoils, and probably for time cert. Why ? A stripped thread is neither a known and consistent diameter nor clean metal. You need to bore to get to usable metal. Then thread to the larger size with the right tap. Yes you can managed to skip the drill to enlarge part, but the results will be unpredictable.....
