M10-1 X 60mm 六角頭螺絲 | 10.9級鋼本色 | 部分螺紋 (400/包)

Grabbed a box of these for a few equipment repair jobs and the hex heads grabbed a socket perfectly every time, no stripped corners. The partially threaded design held firm where I needed full clamping force, and a full box of 400 means I won't be reordering for a while.

I've been using these M10-1 x 60mm bolts for heavy equipment assembly, and the class 10.9 steel holds up perfectly under high torque without any deformation. The partially threaded design makes alignment much easier during installation.

Finally, a bolt that doesn't strip under heavy torque – the hex head gripped perfectly with my socket wrench. The partially threaded design was exactly what I needed for assembling a steel frame, and the class 10.9 steel feels rock-solid. For the price of a 400-pack, this is unbeatable value.
