Fifty in a pack and every single one has a clean, uniform thread—no binding or galled threads when I ran them into my jig. The black oxide finish looks great and held up fine during assembly. These are going straight into my tooling drawer for the next project.

I needed some decent fasteners for a jig I was building, and these cap screws fit perfectly without any slop in the threads. The black oxide finish looks clean and professional, and they held up well under moderate clamping pressure during assembly.

The low head design on these screws made a big difference in a tight clearance spot on a jig I was building. They threaded in smoothly and the black oxide finish looks clean. Only minor thing is the package had a couple with slightly uneven threads, but overall a solid value for the price.
