Customer Reviews (4.2 / 5 · 5 reviews)

Stella ★★★★★

The black oxide finish on these is flawless—no chips or rough edges across all 500, and the hex sockets are cut perfectly true. I ran them into a jig plate and every one torqued down smooth without a single stripped head. For the price per piece, you can't beat this level of consistency.

Lucy ★★★★★

Got these for a precision assembly and the hex socket drive makes tightening them in tight spots much easier. The black oxide finish looks durable and they thread cleanly into tapped holes without binding.

David ★★★★☆

I needed a full box for a jig project and the 3/8-24 thread cut cleanly all the way through. The thermal black oxide looks even and hasn’t flaked despite some wrench contact, so only minor gripe is the packaging could be sturdier.
