Brian ★★★★★

Picked up a pack for some jig work I’m doing, and the hex socket drive makes tightening these a breeze in tight spots. The black oxide finish also seems pretty durable, no chips after installing a few dozen.

James ★★★★★

I needed exact M2.5-0.45 screws for a jig I'm building, and these 20mm ones fit perfectly with the hex drive. The 600-count pack means I’ve got plenty left for future projects, and the Class 12.9 alloy steel feels solid.

Isabella M. ★★★★★

The black oxide coating on these screws gives just enough grip for precision work without slipping, and the 12.9 alloy steel feels rock-solid when tightening. They fit perfectly into my small jig build, and having all 600 in one pack saves me from reordering mid-project.
