Customer Reviews (4.6 / 5 · 5 reviews)

Owen ★★★★★

The black oxide finish on these screws gives them a clean, professional look that resists fingerprints during assembly. I’m using them for a metal enclosure project and each one threads smoothly without binding.

Charlotte ★★★★★

I needed a bulk supply of small fasteners for a metal project, and these #4-40 screws with the black oxide finish hold up nicely against rust. The Phillips drive seated well without stripping, and the flat 100° head sat flush in the counterbore.

Brian K. ★★★★★

These little screws worked perfectly for a small electronics project where I needed a low-profile black fastener. The Phillips drive seated nicely without camming out, and the 100-count bag had no missing or damaged pieces.
