Customer Reviews (4.6 / 5 · 5 reviews)

Carter Y. ★★★★★

Installed these in a jig for a small CNC project and the fit was spot on—no wobble or stripped threads during tightening. The hex socket grabs the driver firmly, which made assembly much easier than with slotted screws.

Madison N. ★★★★★

The black oxide finish on these screws gives them a nice grip, and they threaded perfectly into my aluminum tooling jig without any stripping. They're exactly the right size for precision assembly work.

Ruby W. ★★★★★

I needed some precise fasteners for a jig build and these #5-40 x 1" screws seated perfectly with the hex drive. The black oxide finish looks clean and seems durable.
