Used these for a jig I was building that needed shallow clearance. The black oxide coating looks good and seems to resist rust so far. They held up fine under moderate torque without stripping.

I needed these for a jig I was building, and the black oxide finish is holding up well against minor scratches during assembly. The hex socket drive gave a solid grip without stripping, which was my main worry with cheaper screws.

These low head socket cap screws fit perfectly in my jig setup where clearance was tight. The black oxide finish looks clean and the class 10.9 alloy steel feels really solid for the price. Exactly what I needed for a precise assembly.
