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.

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.

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.
