M18-1.5 X 70mm 外六角螺絲 | 8.8級鋼本色 | 部分螺紋 (20 / 包)

The partial threading on these M18 screws was exactly what I needed to secure a heavy frame without bottoming out. The hex heads gripped my socket firmly and the 70mm length worked perfectly.

Class 8.8 steel means these hex heads hold up under serious torque without stripping, and the partial threading made aligning them in the equipment frame way easier than full-thread bolts would've been. They came in a neat 20-pack, so I've got spares for the next job.

These were the exact thread pitch and length I needed for a jig I’m building, and the partially threaded shaft grabbed tight without any wobble. The hex heads seated cleanly in my socket, and the whole pack of 20 arrived without a single burr or ding.
