You’ve stripped the stud on your car / motorcycle / whatever. Sure you could just tap a new thread, but if you were in my situation, a stripped stud in the soft aluminum of the final drive of your motorcycle, it does not really solve the problem. I would still have been screwing in a steel bolt into softer aluminum and would have been at risk of stripping again. With these I am putting in tough steel threads, which will not have that problem.I did not want to heli coil, as my final drive contained oil, and the heli coil seemed like it could leak and wasn’t as permanent. There are also reports of people heli coiling their oil pans and getting slight leaks. Install was super easy and fast, and I have no worries that it will ever fail on me.Tip: I used some red (permanent) locktite around the threads of the insert just to be double sure it would stay in place, even though the documentation states that it is a ‘self locking’ insert….can’t hurt to play it safe.

There is no better way to correct stripped threads. Wish there was a multi-size kit. Would be a fantastic addition to any garage.

This is much stronger and solid compared to a normal helicoil. I had a manifold bolt break and the aluminum threads all stripped out of the head on my Jeep. It was a long process as it was near the firewall and we had limited room to work. Once it was done the bolt went in perfectly and is holding tight and snug. Would highly recommend to anyone in the same situation as i was. Excellent product!!!!!!

2003 Chevy Malibu 3.1 174000 miles Rocker bolt thread repair – Cylinder 4.(Post your vehicle specs to help others!)First off, Its made in the USA. Very good quality and works very well. The hold down bolt for the #4 cylinder pulled out. I found the rocker just sitting there. The time to completion was about half an hour. Most of that is prep work and clean up. The actual repair should only take about 10 minutes or less – Im not a mechanic. I have seen some reviews of people complaining about breaking the bits in the package. They must be doing something wrong as these are good quality and should never break especially when used on the aluminum head. The kit comes with everything you need including five serts. These are 8mm 1.25 thread serts. GM upgraded the bolt size later to 10mm because of this problem. Make sure you select the correct kit size. Measure the rocker bolt with a caliper. Mine actually measured about 7.40mm approx. Therefore you would use the 8mm kit. (1812).This is the first time I have used the time-serts. I thought the hardest part would be to make sure I was parallel to the bolt hole when drilling out the old threads. In all actuality, Using the bit to create the collar is more critical. If you do not get the collar for the sert correct it will be above the surface of where the rocker arm goes on. Your going to have to then take something like an easy out to remove it and correct your problem. In hindsite, After you drill your collar take an insert and set it in upside down (collar down) and check to make sure it is evenly drilled and below the level of the rocker mounting. I think if you screw up this will be where you will do it in the whole process. Taping the insert threads and installing the insert is the easy part. I would like to point out that the reason I did not give it 5 stars is because the collar bits guide seems to be much smaller than the 8mm bolt hole after drilling out the threads. This can cause you to be not centered on the bolt hole. Be nice if it was more of a snug fit. However, When drilling the collar just go slow and at first just let it scratch the surface and then check your alignment. If it looks good then go for it. If you make a mistake then its not too bad. Just more over a bit and remove some more material so the collar fits as it should.When drilling and taping your going to need some tools to make the job easier. A regular tap is too short with everything in the way unless you actually removed the valve head. Lisle 70500 tap socket set is your friend. You can then attach an extension to the tap(s) and use a ratchet. Remember also grease or oil is important. Not a ton but just enough to get the job done.One garage wanted 900.00 to fix this. An other said to just junk the car. I fixed this for the cost of this kit and the tap socket set from Lisle.One last comment here: Do not use the heli coils. These are not as strong as the solid inserts in this kit. Heli coils are fine for simple repairs that do not experience a lot of force – not like a rocker arm.

Stripped a stud on one of the cylinders of my old BMW. Freaked me out. Bought this kit on recommendation by a Restauration expert. Diligently follow the steps using different types of bits. Final results es really good.

I’ve used heli-coils for repairs in the past and they have worked well. However, this stripped hole was on a part that took many days to get the housing accessible and I wanted a highly reliable repair. The kit is well packed and protected, appears to be high quality, and worked smoothly for this repair. The final condition almost made me want to ‘fix’ the surrounding holes (that were perfectly ok). Bottom line: expensive as I needed the full kit to start but worth the investment for this task. If the hole was in a more readily accessible location, I would have just picked up the heli-coil size and used my existing drill and die set. However, now that I have the set, it will be my first choice in the future.

I purchased this to repair a snapped off injector rocker bolt on my 2003 ALH Golf. Worked great, just take your time and go slow drilling the old bolt out.
