M18-1.5 X 80mm 六角頭帽螺絲 | 8.8 級鋼 鋅鍍 | 部分螺紋 (15 件/包)

Used these on a press frame rebuild and the partial threads grabbed clean without binding halfway in. Zinc finish looks uniform across all fifteen, and the hex heads seated perfectly with a standard socket.

I needed some heavy-duty bolts for a trailer hitch repair, and these 80mm M18s drove in cleanly with no thread binding. The partial threading helped them seat perfectly through the thick steel bracket.

The zinc coating looks great and the threads are clean, no burrs or rough spots anywhere. They seated perfectly with a socket wrench on my equipment stand, and the partial threading gave me just the grip I needed.
