M5-0.8 X 80mm 外六角螺絲 | 8.8級鋼鐵原色 | 半牙 (1300 / 包)

The partial threading on these M5 bolts made aligning them into my steel frame a lot easier than fully threaded ones. At 1300 per package, the price per screw is excellent for a production run. I was surprised at how consistent the hex heads are—no wobble in my socket wrench.

My torque wrench clicked at the right setting on every single one of the first batch I used for a jig build, and the hex heads all seated cleanly in my sockets without any stripping. For a full box of class 8.8 partially threaded M5s at this price, the consistency is hard to beat.

Pulling these out of the box, the threading is clean and uniform across the whole batch. The 80mm length worked perfectly for a jig I'm building, and the hex heads seated firmly with a standard wrench.
