M12-1.75 X 30mm 六角頭螺絲 | 10.9級鋼 素面 | 全牙 (450顆/包)

Used these to rebuild a conveyor drive yesterday, and the fully threaded grip made alignment much easier than partial thread. The 10.9 hardness cut down on my torque wrench time noticeably.

Had to swap out a dozen bolts on a press brake and these threaded in clean without any binding, the hex head grip is solid even with a worn socket. The class 10.9 steel feels reassuringly dense when you torque them down. For the price per piece, I've got a lifetime supply now.

The hex heads seated perfectly with a 19mm socket, and the 10.9 grade gives me confidence for our press frames. Only downside is the packaging could be sturdier for such heavy fasteners—had a few loose when the box arrived.
