Customer Reviews (4.6 / 5 · 5 reviews)

Aurora I. ★★★★★

Used a handful of these to fix a worn-out tooling fixture in my shop and the black oxide surface made them slide right into the threaded holes without any binding. They've got that solid, heavy feel you want in a precision assembly bolt.

Robert S. ★★★★★

Needed a few for a tight jig assembly and the 5/16-24 threading caught perfectly without any galling. The alloy steel feels solid and the black oxide finish wipes clean easily.

Brian ★★★★★

The black oxide finish on these screws looks great and seems like it'll hold up well in my jig setup. They threaded in smoothly without any binding, which I always appreciate. Exactly what I needed for some precision tooling work.
