Robert W. ★★★★★

The black oxide finish on these screws gave a nice, uniform look on my tooling jig, and the hex drive seated perfectly without any stripping. They held firm under moderate torque during assembly, which is exactly what I needed.

Richard ★★★★★

Installed these on a jig fixture I’m building for repetitive clamping, and the hex socket drive made tightening precise without stripping. The alloy steel feels solid, threads were clean out of the pack. Just what I needed for a durable assembly.

Violet U. ★★★★★

The black oxide finish held up fine during assembly, though I did have to wipe a bit of excess oil off the threads before torquing them down. Drove cleanly into my fixture plates without any stripping.
