Customer Reviews (5.0 / 5 · 5 reviews)

Chloe ★★★★★

Used these to mount a jig plate on the drill press and the flat head sits perfectly flush. The black oxide finish seems durable, and all 100 screws threaded smoothly with no binding.

Jason P. ★★★★★

Installed these in a busy production fixture and the black oxide finish hasn't worn off after a few hundred cycles. The hex socket drive fits perfectly without any wobble.

Richard O. ★★★★★

Used a handful of these for a jig I was building and the hex socket drive held up perfectly under repeated tightening. The 1/4-20 threads seated cleanly with no cross-threading, which is exactly what I need for precision work.
