M6-1 x 30mm 外六角螺絲 | 10.9級鋼鍍鋅 | 全螺紋 (2200入/包)

I needed a large batch of M6 bolts for a production run and these came fully threaded with a consistent hex head fit, making assembly smooth. The zinc plating is holding up well so far with no sign of rust, even in a slightly damp shop environment.

Had to replace the bolts on a vibrating conveyor line and the class 10.9 steel on these held up perfectly where cheaper ones kept snapping. The zinc plating looks clean and not a single stripped head in the whole 2200-count batch.

Bought these for tightening down the conveyor brackets on our assembly line, and the Class 10.9 rating holds up much better than the Grade 8.8s we used before — no stripped heads. At 2200 per package, these should last through the next couple maintenance cycles.
