M12-1,5 x 140 mm zeskantbouten | Klasse 10.9 staal blank | gedeeltelijk draad (125/stuk)

The partially threaded design made these perfect for securing heavy steel brackets without bottoming out, and the hex heads gripped nicely with a 19mm socket. I've already used about 30 of the 125 for mounting a conveyor frame, and they've held torque well so far.

These 125 screws arrived in one solid box, and the 10.9 grade steel feels seriously tough compared to the usual 8.8s I’ve used. The partial threading makes seating them in a blind hole much easier, and the hex heads grab a socket cleanly without any stripping.

Had to drive these into a steel bracket for a pallet rack repair, and the partial threading made alignment much easier. They seated well with a socket wrench, though I wish the hex head was a hair taller for better grip.
