Your cart is empty.TIME-SERT is a sophisticated thread repair system that is considered by many to be superior to any other method of repairing stripped or damaged threads. TIME-SERTis a solid bushing insert. This facilitates easy installation and allows for full torque to be applied to repaired threads, ensuring a strong, permanent repair. TIME-SERTis thin walled due to synchronized internal / external threads. Small outer diameter allows for installation in areas where clearance is critical. TIME-SERTis self-positioning. The flange on the top of the insert will insure that the insert cannot wind down into the newly repaired hole. TIME-SERTis self locking. On installation the bottom internal threads of the insert expand to lock the insert in place.

I over-torqued a head bolt and stripped the threads out of an aluminum engine block. At first I thought the head bolt had snapped, but it came out intact with a nice coil of aluminum threads wound around the threads. Ugh! A local machine shop recommended this tool. If you decide to use this, what you will be doing is drilling a slightly larger hole in the block, then threading it, then screwing in a sleeve that gives you the same sized threads as the original. The next guy who looks at it may never know there was any kind of repair, and I was able to torque the head bolts according to spec, just over 45 foot-pounds. I did make some slight modifications, though. In addition to the tool I'm reviewing, I also bought the head bolt insert- it is twice as long, designed for high torque, and cost less than $5. I bought a longer drill bit, the one included here didn't reach to the bottom of the hole I was working on. I also fabricated a jig that I bolted over the bad bolt hole to make sure that my drill went in straight- necessary because I was drilling into soft aluminum, and going in crooked was a definite possibility. In all, I probably spent a total of $135 for everything, but that was minor compared to pulling the block and buying another one. Got the engine back together and it runs great!

Great product that works better than a helicoil and easy to install. If done right, makes a nice fit. Product was delivered within one day also.

Lord help you if you need these, because you have already thrown wrenches and cursed a lot... after all that these are the solution. They’re a God send.They just plain work, so well in fact they’re holding the clamping loads for my cylinder heads on my ls9 pushing 20psi of boost going on over a year.(Pro tip: if you’re doing the same job the inset on arp studs is deeper than the tool for these so you’ll have to machine the tip of the cleaner/locator tool... part of the cause of that is arp just renumbered duramax studs since they’re m12 instead of m11 like the rest of the ls cars)Disclaimer: I wrote the same review for the inserts themselves

I ordered this, as it seemed almost effortless and it had great ratings, well I was able to repair a stripped 12MM blind hole in an Iron Cast Gear Box, it was easy and yes it was torqued to factory specifications and it held its own! I would highly ecommend this product to anyone!

Time-Sert is an amazing product, it is higher cost, but it makes a crappy situation turn into a kinda fun fix. I enjoyed how well they worked I installed them on other non damaged threads to avoid future problems. This is a fun product to use low frustration levels if you can drill out a thread.

Heavy duty and also self centering counter sink shoulder with counter sink bit. I had to hold a heavy fan hub on the front of a Cummins M11 in in international over the road truck. It is still holding today)
