Customer Reviews (5.0 / 5 · 5 reviews)

Lily X. ★★★★★

The threads cut clean and the black oxide finish has held up well across a few weeks of assembly work on my jig fixtures. These feel solidly made, and the 4-1/2" length gave me plenty of grip without any wobble in the drive.

Steven U. ★★★★★

The hex socket drive seated perfectly on my driver with zero wobble, and the alloy steel thread cut cleanly into the fixture plate on my mill. These hold up great under heavy clamping torque.

Harper ★★★★★

The black oxide finish on these screws held up well against my jig's constant metal-on-metal contact. They threaded smoothly and the hex socket drive didn’t strip even under heavy torque.
