M16-2 x 80mm 六角頭螺栓 | 10.9級鋼原色 | 部分螺紋 (20入/包)

The partially threaded design on these M16s made seating them in my equipment frame much easier than fully threaded bolts—engagement was clean and didn't bind up. Class 10.9 hardness means they're definitely not stripping under my torque wrench, and the hex head fits a standard socket perfectly. Cou

Installed these on a heavy-duty press jig and the 10.9 steel held up without any stretch or strip. The 80mm length was just right for a thick flange, and the hex head gave a solid grip with a socket wrench.

The partially threaded design made these bolts ideal for aligning my heavy equipment frame before fully torquing down. They’re solid and the hex head fit my socket perfectly without any stripping.
