Jason ★★★★★

The nylon pellet on these screws holds tight without galling the threads, and the black oxide finish looks clean on my jig setup. I ordered a full box and every single one threaded perfectly into 5/16-24 tapped holes.

Robert Z. ★★★★★

These cap screws drove in cleanly with a standard hex key and the black oxide finish looks sharp on my jig setup. Threads were fully formed and consistent across the whole pack of 100, which saved me a trip to the hardware store.

Brian ★★★★☆

I needed some strong fasteners for a jig I’m building, and these black oxide screws threaded in smoothly without any binding. The nylon pellet is a nice touch for keeping them from vibrating loose under load.
