Customer Reviews (4.4 / 5 · 5 reviews)

Zoe ★★★★★

I needed these for a jig build and the black oxide finish gave them a nice uniform look without any glare. The hex drive grabbed perfectly with my allen key, no stripping or slipping.

Penelope ★★★★★

The flat head sits perfectly flush in my fixture plates, and the hex socket drive grabbed without any stripping on the first pass. The thermal black oxide finish is uniform across all 100 pieces, no flaking even after tightening them down hard.

Evelyn ★★★★★

Needed black oxide fasteners for a jig build and these fit the bill perfectly. The hex socket drive grabs securely without stripping, and the finish looks clean. A solid 100-count box for repeat projects.
