M8-1.25 x 140mm 六角頭螺絲 | 10.9級鋼 鍍鋅 | 部分螺紋 (100顆/包)

The partially threaded section grabbed cleanly and seated tight against the frame without any binding, and the hex head took a socket wrench without rounding. For 140mm of 10.9-grade steel at this price, these hold up way better than the cheaper hardware I’ve used before.

Wrenched these into place on a piece of equipment and the hex head grabbed the socket perfectly, no slipping. The zinc plating looks even and clean, and the 10.9 steel feels solid enough that I’m not worried about them snapping under load. For the price, a solid box of bolts.

The partial threading made these bolts perfect for clamping a thick steel bracket without wasting length. They seated cleanly with a standard socket and the zinc coating seems durable for outdoor use.
