Brian E. ★★★★★

The black oxide finish on these screws looks great and seems durable; they threaded cleanly into my jig fixture without any binding or galling. For the price per piece, having 600 precision-ground alloy steel fasteners is excellent value for any shop.

Riley M. ★★★★★

I needed fasteners for a jig build, and the black oxide finish on these M4 screws gives them a nice, consistent look without any burrs. The class 12.9 rating means I can really torque them down without worrying.

Abigail ★★★★★

These were perfect for mounting a small jig on my mill; the black oxide finish looks great and the hex drive seated cleanly without stripping.
