M7-1 x 12mm 六角頭螺絲 | 等級8.8 鋼 鍍鋅 | 全螺紋 (300個/包)

Packed a full day of light machinery assembly and only used about half the box—the hex heads hold up well under torque without stripping. The 12mm fully threaded length bites just right for what I needed.

These are perfect for rebuilding a small gearbox I’ve been working on; the 12mm length is just right, and the hex head lets me get a firm grip with my socket. The zinc plating looks clean and seems like it’ll resist rust well in my shop.

Used these to bolt down a heavy assembly table and the 12.9 hardness held torque perfectly with zero stripping. The zinc coating looks clean and uniform across all 300 pieces.
