M8-1.25 X 80mm 內六角螺絲 | 平頭六角驅動 | 部分螺紋 | 10.9級合金鋼鍍鋅 (100顆/包)

The partially threaded design on these M8 bolts made fine-tuning a motor mount surprisingly easy, and the zinc coating looks clean. They tightened down smoothly with a hex key and held firm under heavy load.

I used these for a custom jig in my shop, and the hex socket drive made installation much easier than with standard hex bolts. The zinc plating seems durable and should resist rust well over time.

The partial threading on these M8 bolts made them perfect for a tight alignment on a machinery stand. They drove in cleanly with a hex key, and the zinc plating looks solid. A straightforward solution for precision assemblies.
