Sofia Y. ★★★★★

The black oxide finish on these flat heads gives a nice uniform look against the steel frame I used them on. They seated perfectly flush without any stripping issues.

Matthew F. ★★★★★

I've used about forty of these so far on a jig fixture and the flat head seats flush every time without stripping, the hexagonal drive grips the wrench firmly. For three-eighths length they feel solidly machined, and the thermal black oxide hasn't chipped or rusted after a few weeks of shop use. Exa

The black oxide finish on these screws gives them a clean, professional look that holds up well during assembly. I used them for mounting brackets on a small machine, and the flat head sits flush perfectly.
