M12-1.5 X 55mm Sechskantschrauben | Klasse 8.8 Stahl blank | Vollgewinde (50 / Packung)

Used a full box of these on a new assembly line build and every single one seated perfectly with no cross-threading. The 8.8 steel gives them plenty of strength for heavy-duty framing work, and the hex head design made them easy to tighten even in tight spots.

These are the exact thread pitch I needed for the motor mounts, and the 8.8 grade steel feels properly hefty in the hand. The hex head sits flush with a standard socket and they all threaded in clean without any galling. A solid, no-fuss buy for industrial work.

Needed a full thread to seat properly in a tight bracket assembly, and these 55mm M12s cut through the steel clean without stripping. The class 8.8 hardness held up under a serious torque wrench, and the hex drive grabbed perfectly every time.
