The black oxide finish on these screws looks great and seems like it'll hold up well in my shop jigs. The hex socket drive made tightening them down with a ball-end Allen key really easy, even in a tight spot.

The black oxide finish is spot on for my jig builds, no glare and it grips the hex wrench nicely. Threads ran clean into my fixture plate without any binding, and the partial thread gave me just the right grip depth. These feel solid enough to trust under load.

Had a tricky alignment on a press tool and these flat heads seated flush with zero wobble. The hex socket drive made tightening them fast and precise, even in a tight spot.
