M12-1.25 x 40mm 外六角螺絲 | 8.8級鋼 黃鋅鍍層 | 全螺紋 (350個/包)

I needed these for mounting some heavy equipment, and the Class 8.8 steel feels plenty strong enough for the job. The yellow zinc coating gives them a nice uniform finish, and the hex head fit my socket perfectly.

The fine thread pitch on these grabbed nice and tight when I torqued them down on my equipment frame—no stripping or galling. Yellow zinc finish looks evenly coated across all 350, and the hex heads seated cleanly with a socket. Solid buy for the price.

Had to swap out some worn bolts on a press jig, and these M12s threaded in cleanly without any binding. The yellow zinc finish is consistent across all 350 pieces, and the hex heads gave my socket a solid bite.
