I've been using these for building custom jigs, and the hex drive makes them so much easier to work with than Phillips; they don't strip when I tighten them. The nylon patch is a nice touch too, it keeps them from vibrating loose on my machining fixtures.

The black oxide finish on these screws looks clean and professional. I used them for a small jig assembly, and the hex drive seated perfectly every time. Exactly what I needed for precision tooling work.

The nylon patch on these screws holds tight even with vibration—perfect for securing a small tooling fixture I built. They drive cleanly with a hex key and the black oxide finish looks professional.
