M12 X 80mm 平頭內六角止付螺絲 | 合金鋼 (50入/包)

The hex socket drive made these easy to tighten in a cramped machine area, and the 80mm length was exactly what I needed. Each screw threaded smoothly without any binding, and the alloy steel feels solid for heavy-duty use.

Needed a set for a tight alignment job and the hex socket drive let me really crank them down without stripping. The flat point seated perfectly against the mating surface, and all fifty came in a solid cardboard box.

I was able to get these M12 x 80mm screws torqued down perfectly in a cramped spot thanks to the hex socket drive. The flat point tip seated cleanly without any slipping, and the alloy steel feels solid. A great pack for the price.
