Customer Reviews (5.0 / 5 · 5 reviews)

Sebastian ★★★★★

The black oxide finish is even and tough—these held up fine when I torqued them into a steel fixture without any galling. The partially threaded design grabbed cleanly and the hex socket seated perfectly with my driver. Exactly what I needed for a heavy-duty tooling setup.

Lucy W. ★★★★★

Installed these on a jig I’m building for a custom fixturing setup—the hex socket drive made tightening in tight spots much easier, and the black oxide finish looks sturdy enough for the job.

Nicholas ★★★★★

Had to replace a worn screw on a heavy-duty press fixture, and these black oxide ones fit perfectly with no slop in the hex drive. The partially threaded design made installation a breeze, and they feel much more robust than standard hardware store screws.
