M22-2.5 X 100mm 六角頭螺絲 | 10.9級鋼鍍鋅 | 部分螺紋 (80個/包)

The hex heads on these bolts gripped my socket perfectly without any slipping during installation. For heavy machinery assembly, the 10.9 grade steel feels reassuringly strong and the zinc coating looks like it'll fight rust well.

These M22 bolts fit perfectly in my press jig, and the zinc plating on the class 10.9 steel already looks like it will resist rust way better than the uncoated ones I used before. The partial threading made it easy to get a clean start with a socket wrench.

I needed some high-grade bolts for a heavy equipment repair, and the partially threaded shank on these M22 screws gave just the right grip depth. They’re solid 10.9 steel and the zinc plating looks clean—no burrs or defects in the whole package of 80.
