Customer Reviews (5.0 / 5 · 5 reviews)

Ruby ★★★★★

Grabbed these for a jig I'm building and the black oxide finish wiped clean with just a rag, no oil film left behind. The 12.9 hardness is evident the moment you feel the weight, and threading them into a tapped block was buttery smooth with zero galling.

Ava ★★★★★

Had to torque these down pretty hard and the hex socket didn't strip at all—the alloy steel feels seriously tough. Fit perfectly into the jig I'm building.

Thomas G. ★★★★★

The hex socket drive made installation effortless with my T-handle wrench, and the black oxide finish on these M16s looks clean and professional on my assembly fixture.
