Needed these for a jig I was welding up, and the 12.9 alloy steel handled the torque perfectly without snapping. The zinc plating also kept them rust-free after a few days in a damp shop.

The hex socket drive seated perfectly on my torque wrench without any cam-out, and the zinc plating on these M12 screws has a clean, even finish that resists rust well. I used them to secure a heavy-duty press brake jig, and the fully threaded length held firm under high clamping force.

The zinc plating looks consistent across all fifty pieces, and the hex sockets are cut cleanly enough that my 10mm Allen key seats without any wobble. I've used them to lock down a steel fixture plate and the 12.9 hardness gives me confidence they'll hold torque.
