M14-1.5 × 30mm 內六角螺絲 | 六角驅動 | 全螺紋 | 12.9 級合金鋼鍍鋅 (50 顆/包)

The zinc plating is a nice touch, hasn’t rusted after a week of sitting on my bench in a humid garage. The 12.9 alloy steel feels seriously solid, and the hex socket drive seated perfectly in my wrench without any wobble. These are going straight into my tooling setups from now on.

I put these in a jig for a production run and the hex drive held up perfectly, even under repeated torque. The zinc coating looks clean and consistent across all 50 pieces, with no burrs on the threads.

Used a full bag mounting a custom steel fixture, and every bolt threaded cleanly without any binding. The hex drive engaged perfectly with the allen key, and the zinc finish looks consistent across all 50 pieces.
