Kevin ★★★★★

Needed exactly 2000 for a project, and these were the right size and thread for the job. The flat head sits flush and the black oxide finish looks clean.

Julian P. ★★★★★

The black oxide finish on these screws is a nice touch—it makes them look professional and seems to resist scratches better than plain stainless. I used them for mounting some small electronics brackets, and the thread rolling action bit into the plastic perfectly without any slipping.

Abigail D. ★★★★★

I needed a bulk supply of small screws for a project and these fit the bill perfectly—the Phillips drive made installation quick, and the black oxide coating gives them a clean, professional look.
