Customer Reviews (4.6 / 5 · 5 reviews)

Emma Y. ★★★★★

The thermal black oxide finish on these cap screws gave my jig a clean, professional look, and the hex socket drive held up perfectly under torque. They threaded smoothly into my assembly without any binding, which was a pleasant surprise for such a large fastener.

Nicholas W. ★★★★★

I needed cap screws with a bit more grip length for a jig I was building, and these partially threaded ones fit the bill perfectly. The black oxide finish looks solid and the hex socket drove smoothly without any stripping.

Miles ★★★★★

The black oxide coating on these screws is a nice touch—they look professional and resisted scuffs during assembly. Used them for a jig build, and the hex socket drive made tightening in tight spots a breeze. Just what I needed for precision work.
