M12-1.75 X 240mm 六角頭螺絲 | 8.8 級鋼鍍鋅 | 部分螺紋 (25 顆/包)

Needed these for a trailer hitch build, and the 240mm length paired with the partial threads gave just the right grip depth. They torqued down smoothly without any binding.

The zinc plating looks factory-tight and uniform across all 25 pieces, so no rust worries after a week of outdoor use on my press jig. These class 8.8 screws torqued down smooth without any thread binding, and the partial threading grabbed just right for that 240mm reach.

These bolts handled the heavy brackets on my workshop shelving perfectly. The 240mm length and partially threaded shaft let me get a solid grip in the steel frame without fighting the threads. The zinc coating on the Class 8.8 steel looks durable and clean.
