M24-3 x 75mm 外六角頭螺絲 | 10.9級鋼 鍍鋅 | 半牙 (50入/包)

The zinc plating looks flawless and the threads are clean right out of the box, so they seated without any binding on the flange I bolted down. Class 10.9 is overkill for most jobs, but for this price per piece it's nice having that extra safety margin on a critical joint.

The hex head on these M24 bolts really grips the socket firmly, no slipping even when I torqued them down tight. Nice solid feel for heavy equipment assembly work.

The partial threading on these M24 bolts made alignment much easier when I was tightening them down on a heavy equipment frame, and the zinc plating looks clean. They fit perfectly with my socket wrench and held torque without any stripping.
