M10-1.5 X 30mm 內六角螺絲 | 六角驅動 | 全螺紋 | 12.9級合金鋼鍍鋅 (100顆/包)

The hex socket drive on these screws gives a solid grip even with worn Allen keys, which I appreciate when tightening 30mm bolts in tight spaces. The zinc coating holds up well against minor spills in my garage setup.

I use these for building jigs in my workshop, and the fully threaded length on a 30mm M10 is exactly what I needed for clamping thicker plates. The zinc plating has held up fine so far, no rust after a few weeks of shop use.

Picked up a pack for repairing a fixture on my mill and the hex socket drive is clean and precise, no wobble when torquing. The 12.9 alloy steel feels noticeably tougher than the standard bolts I had before, definitely worth the upgrade.
