M12-1.75 x 16mm 外六角螺絲 | 10.9級鋼原色 | 全螺紋（600個/包）

The hex head on these takes a standard socket perfectly, no slipping or rounding. Worked great for securing some heavy machine guards.

The hex head holds perfectly with a standard 19mm socket, and these M12 bolts came fully threaded which saved me time on a machine guard project. They're surprisingly solid for the price, and the 600-count pack should last me through several maintenance cycles.

The class 10.9 steel rating gives me confidence these won't strip under heavy torque. Fully threaded design made it easy to get a secure bite in my equipment assembly.
