I used this to fix threads that I messed up using heli-coil. It works great. Followed the instructions. I would say they are easier to install and better overall than the heli-coils.

I had 2 bolt holes on an aluminum head for a timing chain tensioner that was wallowed or not completely round anymore. Previously, I used a permacol that did not hold up. This product worked as advertised to save me the trouble of pulling the engine head and taking it to machine machinest to fix.The kit comes with everything you need to install the Bigsert except for a tap handle. I just used a vice grips.

Fantastic solution, glad I finally bought this. Easy to use, very high quality tool in my opinion.

Used these to repair several camshaft cap bolt holes in an old Kawasaki several years ago after ruining the original threads and helicoil repairs (I blame my stubbornness and improper torque spec). So far zero issues, and plan to use Time-Sert to repair a stripped oil drain plug (this time, it was a previous owner).

I accidently drilled my last hole on a salvaged bike a little too big. I origionally bought a normal heli-coil set, but due to the larger hole, the blt was leaking oil, and I couln't properly torque bolt. This set, the way it's designed, doesn't allow for oil to wick past where the big sert mates to the engine case. The instructions say to oil the insert tool before inserting the big-sert, which I find as a must. I took it one step further and applied an oil resistant silicone to the outside of the big-sert where it mates to the engine block and that solved my problem.

I'll never use another Helicoil again. Time-Sert is so much cleaner, even after I boogered the hole (with a Helicoil that broke) and had to go oversized.
