Customer Reviews (4.8 / 5 · 5 reviews)

Victoria ★★★★★

I needed a batch of strong screws for a jig I’m building, and these came perfectly threaded with the nylon pellet already set. The hex socket drive made installation easy with my Allen wrench, and the black oxide finish feels durable.

Penelope ★★★★★

The black oxide finish looks great and seems durable, and the hex socket drive made installation really easy. Used a few of these on a jig I built last week and they held tight with no issue.

Olivia ★★★★★

The nylon pellet on these screws worked perfectly for locking them in place on a tooling fixture, and the black oxide finish looks great. I’ve used about half the pack so far with no stripped heads or threading issues.
