Used a full pack building jigs for the shop, and the 12.9 alloy steel drove in without a single stripped head. The partially threaded length gave just the right grip, and the black oxide finish has held up well against rust so far.

The black oxide finish on these screws is even and durable, so they’ll hold up well in my jig builds. The hex socket drive made installation straightforward with no stripping, even at 90mm length. Exactly the precision fasteners I needed for a heavy-duty fixture.

I needed partially threaded M10 bolts for a jig build at work, and these 90mm socket cap screws fit perfectly. The hex socket drive made installation easy with a standard wrench, and the black oxide finish seems durable.
