Customer Reviews (5.0 / 5 · 5 reviews)

Lucy ★★★★★

Used these for mounting a custom tooling fixture and the hex socket drive made installation straightforward even in a tight spot. The black oxide finish is holding up well in my shop environment.

Emily ★★★★★

Installed these on a heavy press jig and the black oxide finish held up well against the shop grime. The hex socket drive gave me a solid grip even with a long extension bar.

Joshua ★★★★★

Threads cut perfectly clean when I ran the tap through, and the black oxide finish held up great against the coolant spray on my mill. The 12.9 hardness is exactly what I needed for a high-torque fixture; no flex at all under load.
