Finally, a US-made screw that isn't stripped before it leaves the bag. The thermal black oxide finish has a nice, even grip that makes seating the hex socket drive feel precise in a tight jig. These are exactly the right length for my small fixture plates.

The hex socket drive on these screws took my hex wrench cleanly without any stripping, which is exactly what I need for fine adjustments on my drill jig. The black oxide finish looked even and consistent across all fifty pieces, too.

Installed these in a tight jig assembly where standard screws wouldn't fit, and the 1/8" length was exactly what I needed. The black oxide finish slides in smoothly and holds up well under repeated adjustments.
