The black oxide finish on these socket cap screws is flawless, no burrs or rough edges anywhere across the whole hundred. I've torqued them hard on a precision fixture and the hex drive hasn't stripped once, which is exactly what I need for repeated setups.

I needed some high-strength fasteners for a jig I was building, and these screws turned out to be a perfect fit. The hex socket drive made installation smooth even in tight spots. Good value for a hundred pack.

The black oxide finish on these screws looks great and seems durable, and they've held up perfectly in my jig setup so far. I really appreciate how consistent the threading is across the whole pack, making assembly much quicker.
