Natalie ★★★★★

The nylon pellet in the threads is a nice touch, locks them in place without needing threadlocker. I used these for a small jig assembly and they cinch down cleanly, the black oxide finish looks sharp against the steel.

Stella ★★★★★

Installed these in a fixture plate today and the nylon pellet held the set screw adjustment perfectly under vibration. The black oxide finish looks sharp and the threads cut cleanly without any galling. Exactly what I needed for tooling work.

Lucy ★★★★★

The nylon pellet on these screws really locks them in place on my tooling jigs, no more backing out under vibration. Threads were clean and started easily in tapped holes. Good value for a hundred pack.
