High quality replacement turbo bolts
These bolts are exactly what I needed to replace the old ones on my turbo. Strong steel, perfect fit, and very reassuring when reassembling.

Perfect
This tiny O-ring makes all the difference. I installed it on my Garrett turbo, and it keeps perfect pressure with no leaks. Super durable and precise, way better than generic ones.

Outlet bolt set
Bolts appear to be of good quality!

The bolts threaded in,
the problem is the washer head is to small ,it ducked into the housing. I put on a 1/4 " flat washer, and it worked. I found a fix mentioned above

Order these
I failed to include these on my initial order of parts to rebuild my turbo and had to make another order. You definitely don’t want to reuse any of your original bolts from the exhaust/turbine side. Order two or three packs of these and you’ll be good. TP38 requires 3 for the exhaust outlet, four to bolt the center cartridge to the turbine housing, four to bolt the compressor backplate to the center cartridge, and four to bolt the compressor housing to the compressor housing backplate.
