Black oxide finish looks sharp and holds up well on the jig I built, plus the hex socket drive makes seating them in tight spots a breeze. Every one of the fifty threaded clean without any binding, which is rare at this size.

These little #2-56 screws threaded perfectly into my milling jig with no binding, and the black oxide finish looks clean and professional. Exactly the right size for precision work, and the hex socket drive makes installation a breeze.

The black oxide finish on these is flawless and uniform, which makes them slide into tight spots without any galling. I used a full pack on a jig build and every single screw threaded cleanly with zero duds.
