Never used these before a friend suggested I do. Worked great and that worry is now out of my mind.

Appear to be well constructed, coating is nice and the threads were clean. Dont have a ton of miles on them yet but they assembled nicely onto the engine and all is good so far.

Ya get what ya pay for. I ended up buy some Comp rocker stud nuts. This may work for some piticular engine but not the small block Chevy I worked on.

These look like hi grade stuff and should be just the ticket for replacing the old jam nuts on my SBC, nicer for setting and locking in lifter plunger depth @ 0.018" with two flats from zero lash.

Good solid product, easy to install. Terrific value for the price. Highly recommend these Poly Locks to replace stock self tightening rocker stud nuts when utilizing adjustable flat tappet hydraulic lifters or mechanical flat tappet cams.
