M6-1 X 80mm 六角頭螺絲 | 8.8 級鋼黃鋅 | 部分螺紋 (200 顆/包)

The partial threading on these M6 bolts made them ideal for the machinery mount I was working on; the hex head took a socket wrench without slipping. Yellow zinc finish seems durable so far, and for 200 pieces, you can’t beat the value.

These M6 bolts fit perfectly into the equipment frame I’m assembling, and the class 8.8 steel feels noticeably strong even under load. The yellow zinc coating looks durable too, which is a plus for the workshop environment.

The partially threaded design makes alignment in a blind hole way easier than fumbling with fully threaded bolts. I've used about half the box on a machine frame rebuild and none have stripped or sheared under torque.
