Customer Reviews (4.8 / 5 · 5 reviews)

Owen ★★★★★

The black oxide finish on these screws is consistent across all 100 pieces, which matters when building a jig that has to look clean. They threaded smoothly into tapped holes without binding. Exactly what I needed for a precision tooling project.

Ella J. ★★★★★

Needed a batch of M6 screws for a tight-clearance assembly and these flat head socket caps fit perfectly. The black oxide finish looks clean and seems more consistent than what I've seen on other budget fasteners.

Kevin ★★★★★

The thermal black oxide finish on these M6 socket caps looks sharp and seems to hold up well against scratches during assembly. I've used them on a jig I'm building and the flat head sits nice and flush, which is exactly what I needed for a clean fit.
