M14-1.5 X 55mm 外六角螺絲 | 8.8級鋼鍍鋅 | 半牙 (50個/包)

The zinc plating looks even and clean across all fifty bolts, no flaking or rough spots. I used them to bolt down a steel frame and the class 8.8 hardness gave me total confidence torquing them to spec. Threads started smoothly and the partial thread made alignment way easier than expected.

The partially threaded section made installation a breeze in my press setup, and the zinc plating feels durable enough to resist rust in my damp workshop. These M14 hex bolts fit perfectly with my socket wrench—no stripped heads, just solid fastening.

Needed a sturdy bolt for a tractor linkage repair, and these threaded smoothly without binding. The zinc plating looks clean and the hex head gave the socket a nice, solid grip. Worked perfectly for a heavy-duty fix.
