Customer Reviews (4.8 / 5 · 5 reviews)

Ryan ★★★★★

Pulled these tight into a jig for a machining fixture and the hex socket grabbed perfectly without stripping. The fully threaded design gave me solid clamping force across the entire length of the screw.

Scarlett L. ★★★★★

The black oxide finish on these bolts is exactly what I needed for a jig I'm building—no rust worries after a week in a damp shop, and the 12.9 alloy steel feels rock solid. The threading is clean all the way down, so they seated perfectly into my fixture plates.

Ellie Q. ★★★★★

The hex socket drive made installation straightforward even in tight spots on my fixture, and the black oxide finish looks like it’ll hold up well in my shop. These M20 screws feel solid, definitely the strength I needed for a heavy-duty assembly.
