Customer Reviews (4.8 / 5 · 5 reviews)

Michael H. ★★★★★

These are exactly what I needed to secure a small jig I built. The hex drive made installation simple, and the black oxide finish seems durable.

Miles W. ★★★★★

I needed some small but tough fasteners for a jig I'm building, and these black oxide screws hold up much better than the zinc-plated ones I used before. The hex drive sits nice and snug in the wrench, no slipping even at the 6-40 size.

Stella ★★★★★

Perfectly consistent threads all the way through the pack, which made a huge difference for a precision indexing fixture I'm building. The black oxide finish really helps with corrosion resistance in my workshop environment.
