Customer Reviews (4.8 / 5 · 5 reviews)

Henry ★★★★★

The black oxide finish gave these a nice, uniform look right out of the box, and the hex socket drive seated perfectly on my driver without any wobble. Threads were clean and consistent across all 200 pieces, so they threaded into my fixture plates smoothly. Solid value for precision assemblies.

Benjamin ★★★★★

The black oxide coating on these screws handled the grease and grime from my shop press without any rust, and the hex socket drive made installation quick with my Allen key set. The 12.9 grade steel feels rock solid for my jig build.

Ryan M. ★★★★★

Needed some strong bolts for a custom jig I’m building, and these class 12.9 screws handled the torque without stripping. The black oxide finish feels durable and hasn’t shown any rust after a few days of heavy use.
