Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

The black oxide finish on these screws looks great and held up perfectly during assembly of a small precision fixture, no chips or wear visible after torquing. The nylon pellet does its job too, locking the threads firmly in place. These are a solid choice for shop work that needs to stay put.

Sophia ★★★★★

The nylon pellet in the socket keeps these from vibrating loose—nice touch for jig work. Black oxide finish looks clean and the threading is consistently crisp across all 100 pieces.

Madison ★★★★★

I needed a batch of strong flat head screws for a jig I was building, and these black oxide ones fit perfectly and seated flush. The nylon pellet is a nice touch for keeping them from vibrating loose during use.
