Used a few of these to secure a heavy jig on my mill table and the Class 12.9 alloy steel held up perfectly under load. The partial threading made installation quick without stripping. Exactly what I needed for precision work.

Used these for a custom jig I built in the shop—the hex socket drive made tightening them in tight spots a breeze. Tested them to spec, and the 12.9 alloy steel held up perfectly under load.

The black oxide finish on these screws is holding up well during my jig assembly work, and the partial threading makes alignment much easier. They torqued down evenly with no stripping, and the hex socket drive fits standard tools perfectly. Exactly what I needed for heavy-duty tooling.
