Customer Reviews (4.8 / 5 · 5 reviews)

Ava ★★★★★

I needed tiny screws for a RC car build and these #1-64s fit perfectly into tight spots with the hex drive. The black oxide finish looks clean and seems durable so far.

Kevin ★★★★★

The black oxide finish on these screws gives them a nice, uniform grip in my tooling fixtures, and the hex socket drive seats the allen key perfectly every time. The 200-count pack means I’ve got plenty for multiple jig builds without a reorder.

David Q. ★★★★★

The smaller thread pitch on these #1-64 screws holds incredibly tight in jig fixtures without slipping. I used about half the package for a gauge assembly and every single one seated cleanly and uniformly.
