M10-1.25 X 75mm 六角頭螺絲 | 10.9級鋼本色 | 部分螺紋 (300個/包)

The partially threaded design is exactly what I needed for a tight assembly where full threads would have bottomed out too soon, and the hex heads grip cleanly with a socket. These 10.9 screws feel solid, not flimsy, at a fair price for three hundred pieces.

I’ve used these for securing heavy equipment mounts, and the 10.9 grade steel holds up much better than the standard hardware I had before. The hex heads gave my socket a solid grip without any slipping during torquing. Exactly what I needed for a reliable industrial assembly.

The partially threaded design is perfect for clamping down thick brackets without stripping, and the 10.9 grade handles heavy loads with no flex.
