M3 x 6mm 六角機械螺栓 | 鋼 鍍鋅 | 全螺紋 (100 個/包)

The zinc coating on these M3 bolts seems durable enough to resist surface rust in my damp basement workshop. They thread smoothly into pre-tapped holes without any binding, and the 6mm length fits perfectly for securing small brackets.

I’ve used these in a few small electronics enclosures and the full threading along the 6mm shank made it easy to lock down components without any extra spacers. The zinc coating looks clean and none of the 100 showed any rust after sitting in my parts bin for a week. Solid pick for the price.

These came perfectly threaded and the hex heads made tightening them easy. Used them to fasten a metal bracket and they held snug with zero stripping. Exactly what I needed for that small machine work.
