Stella T. ★★★★★

Exactly what I needed for a jig I was rebuilding — the flat head hex socket drives made seating them flush a breeze. Fit perfectly into my threaded holes without any binding.

Harper B. ★★★★★

The black oxide finish on these screws gives a nice uniform look once installed, and they threaded cleanly into tapped holes without any binding. I've been using them for precision fixture work and the flat head seats flush like it should.

Matthew ★★★★★

Needed these for a jig I’m building and the flat head design sits perfectly flush in the counterbore. The socket drive engaged cleanly without stripping.
