M8-1.25 x 20mm 六角頭螺絲 | 10.9級鋼 無鍍層 | 全螺紋（200顆/包）

The hex head gripped my socket wrench perfectly without any slipping, and the fully threaded shaft gave me plenty of bite in the aluminum bracket I was mounting. For 200 pieces at this price, they're a solid deal for general shop work.

These bolts seated perfectly flush in the bracket I was mounting, and the 10.9 grade steel feels solid enough for heavy use. The hex head took a socket wrench without any stripping, which was a relief after dealing with cheaper fasteners.

Used these on a tractor attachment rebuild and the class 10.9 steel held up perfectly under heavy torque. The fully threaded design made spacing adjustments a breeze.
