William V. ★★★★★

I needed a handful of these for a small jig I was putting together, and the black oxide finish blends in nicely without any extra coating. The threads were clean and started smoothly in pre-tapped holes, so assembly took no time at all.

Timothy W. ★★★★★

The black oxide finish on these #4-40 screws gives them a nice, uniform look, and the hex socket drive made installation a breeze with my allen wrench. Perfect for holding my small jig together.

Elizabeth K. ★★★★★

I needed some precise fasteners for a jig I'm building, and these socket cap screws fit the bill perfectly. The black oxide finish seems durable and the hex drive grabs securely without stripping.
