Kevin Q. ★★★★★

The hex drive on these #6-40 screws fits perfectly with my standard Allen wrenches, no slippage at all. I used them to secure a small jig for my drill press, and the black oxide coating seems to resist rust well in my humid garage.

Matthew H. ★★★★★

The black oxide finish gave these a nice, uniform look, and they threaded cleanly into my jig without any binding. I used about half the pack for a workshop fixture and every screw seated perfectly. Exactly what I needed for precision work.

Evelyn C. ★★★★★

Was a bit nervous about ordering small hardware online, but the threads on these #6-40 screws are perfectly clean and the black oxide finish looks solid. They seated smoothly into my tooling jig without any binding.
