Heli-Coil 55211 12-24 Kit

Used it to repair a stripped bolt hole on one of my older chainsaws. Worked great.

I have an old Plymouth and one of the carburetor base screw thread stripped off in the body. I have a new carburetor and this one is the original and I rebuilt it and it runs great. From over tightening the wing nut, it pulled on the screw which pulled on the soft medal of the carburetor body. So I tracked down a heli-coil thread insert kit for a # 12 machine screw with 24 thread. I wanted this carburetor cause that is all that is wrong with it. Drilled the correct hold slowly while be careful not to let the metal shavings in the carburetor passages. Follow the instructions and proceed slowly! this was a blind hole I am drilling. Okay drilled the hole enough so the insert seats fully. Then I took the tap supplied with the kit. Re-threaded the hole turn a full turn and back out to let out the metal chips. Once I got tho hole tapped enough so the insert will seat, I proceeded with the tool supplied to thread the insert in the tapped hole. made sure no metal chips were left. These stainless steel inserts are stronger than the soft metal. put the screw in about a dozen times, loosen then tighten , this kit saved my carburetor. These things work great! Take you time drilling and cleaning and use some Wd-40 or equivalent on the threads. keep them lubricated and tight. These work! They will work on many other items as well, check for proper size and thread. Make sure threads are cleaned, lubed and torqued properly, you should not have any problems. Thanks Heli-Coil!

First of all I'd like to say that I'm giving the five stars to Heli-Coil for always making great thread repair products. For Amazon on this one I would give them one star, if you noticed the picture the package has been split open and three of the Heli-Coils were removed obviously somebody had bought this removed what they needed and then returned, then Amazon resold it without even noticing that the package had been opened nice. Luckily I only needed one and it's not worth the trouble of trying to exchange the item because I need it immediately and couldn't wait to deal with an exchange.

I've been using HeliCoil products for 20 years, and they're still the best. Comes with a quality tap, insertion tool, and coils. Additional coils are always available. I do miss not having the vinyl pouches the tools used to come in because they make great long term storage containers for a matched tool set (tap, insertion tool, and spare coils). Not having to throw something away because the threads are stripped is still the best part. Any time I can make a repair with quality materials and have it function as good as new is a great day - especially in this case when I'm able to repair the handles on pots and pans lids for my wife to score a few points with her.

This is a must have Heil coil kit for any mechanic, that works on holly carburetor‘s

Worked as well as the pricier products. I have bougnt many heli coils. These are good.

Helicoil is very easy to use.

Compared to what the kit used to have for this price, which included the correct drill bit and an inserting tool with a HANDLE on it which this kitdoes not have. How do you insert these without a damn handle. How stupid can the marketers be to think the removal of a handle for the difference of pennies is going to motivate repeat sales? It's all made in China now anyway. Very disappointing.
