M22-2,5 X 50mm Inbusbout | Inbus-aandrijving | Volledig schroefdraad | Klasse 12.9 Gelegeerd staal thermisch zwart geoxideerd (10 / Verpakking)

I use these for my jig fixtures and the 12.9 alloy steel feels properly rigid—no flex even under heavy clamping pressure. The hex socket drive seated cleanly with a standard Allen key, and the thermal black oxide coating looks uniform across all ten pieces.

The black oxide finish on these screws gives them a sleek, professional look that fits right into my jig setup, and the 12.9 alloy steel feels rock-solid even when I torque them down tight. They threaded cleanly into pre-tapped holes without any binding, so I’ve already ordered another pack.

The hex socket drive grabbed my torque wrench perfectly without any slipping, which was a relief on a tight jig assembly. These M22 screws feel solid and the thermal black oxide looks like it'll resist wear in my tooling setup.
