Matthew ★★★★★

I’ve been using these for mounting fixtures on a milling table, and the hex socket drive made tightening them in tight spots a breeze. The black oxide finish seems durable and hasn’t shown any rust after a few weeks in a humid shop.

Henry ★★★★★

Threads were clean and the black oxide finish is even across every single screw, no nicks or rough edges anywhere. They seated into the jig plate with a satisfying snugness, and the hex drive didn't strip even under full torque.

Emma A. ★★★★★

The hex socket drive grabbed perfectly with my Allen wrench, no stripping or cam-out like cheaper bolts. For the price, getting a full 25-pack of US-made screws this sturdy feels like a steal. These are going straight into my next tooling fixture build.
