The black oxide finish on these screws looks great and resists wear better than plain steel ones I've used before. The hex socket drive engages cleanly without stripping. Exactly what I needed for my tooling fixture.

The black oxide finish on these screws looks sharp and held up fine during my jig build. Threads were clean, and the nylon pellet kept them snug even after a few setups. Solid choice for tooling work.
