Customer Reviews (4.4 / 5 · 5 reviews)

Julian I. ★★★★★

Bought these for a small precision fixture and the hex socket drive really holds up to repeated use without stripping. The black oxide finish looks clean and helps resist light rust in my shop.

Robert L. ★★★★★

I needed a fresh batch for a jig rebuild and these hex drive 1/4-20s seated perfectly with no wobble. The thermal black oxide coating seems more consistent than what I've gotten from other packs, so they should hold up fine in the shop.

Edward ★★★★★

Used these for a jig I'm building and every single one seated perfectly without any wobble. The hex socket drive grabs cleanly and the black oxide gave them a nice, uniform look against the steel plate.
