M16 防鬆螺帽 | 鋼 鋅鍍 (100件/包)

The hex head grabbed my socket wrench perfectly, made installing them on my excavator’s track bolts a breeze. These M16 jam nuts feel solid and the zinc coating should hold up well against our shop moisture.

The zinc plating on these nuts looks uniform and resist rust nicely, which is exactly what I needed for an outdoor equipment project. They thread cleanly onto standard M16 bolts without any binding or cross-threading. A solid, no-fuss purchase that gets the job done.

Threaded perfectly onto my M16 studs without any binding, and the zinc plating looks clean and even across all 100 pieces. Threw a few on with a wrench and they seated snug without stripping, so I’ve already ordered another pack for the next job.
