Customer Reviews (4.8 / 5 · 5 reviews)

Jason ★★★★★

The black oxide finish on these screws held up perfectly during assembly without any galling. For the price of a 200-pack, they’re an excellent value for tooling and jig work.

Chloe ★★★★★

Installed these on a custom tooling fixture, and the black oxide finish held up perfectly against coolant splashes. The hex socket drive seated firmly without stripping, even under repeated torque.

Adam C. ★★★★★

Used these in a jig I built for milling machine alignment, and the black oxide finish held up perfectly against coolant spray. Each screw threaded smoothly without binding, and the hex socket drive made installation a breeze with no stripped heads.
