Nicholas ★★★★★

The black oxide finish on these flat head screws is really clean and even, and the hex socket drive makes tightening them into tight spots a breeze. I used them on a small assembly fixture and the alloy steel feels solid enough to handle repeated torque without stripping.

Violet ★★★★★

I needed stronger hardware for a jig I’m building, and these 11/4-7 x 2-1/2” socket cap screws fit perfectly with no wobble. The hex socket drives smoothly without stripping, and the black oxide finish looks clean.

Robert O. ★★★★★

The black oxide finish on these screws looks professional and resisted wear when I tightened them into a jig fixture. They seated perfectly flush with the material, and the hex drive held firm without stripping. Exactly what I needed for precision assembly work.
