Christopher R. ★★★★★

These flat heads sit perfectly flush in my jig's countersunk holes, and the black oxide coating seems durable so far. They torqued down to spec without any stripping issues.

Eli U. ★★★★★

Got these for a precision assembly I’m working on, and the hex socket drive made installation in tight spots a breeze. The black oxide finish looks clean and seems like it’ll hold up well.

Jason ★★★★★

I needed some strong screws for a jig I was building, and these 12.9 alloy steel cap screws held perfectly with no stripping. The hex socket drive made installation quick and easy with a standard Allen key.
