M30-3.5 X 90mm 外六角頭螺絲 | 10.9級鋼無處理 | 部分螺紋 (3顆/包)

The hex head grabbed my 30mm socket without any wobble, and the partial threading seated perfectly against the flange. These 90mm caps feel rock solid for the price of a three-pack.

The threads cut cleanly and seated fully with a standard socket, no binding at all on the first pass. These class 10.9 bolts feel rock-solid for the heavy equipment frame I'm bolting up, and the partial thread gives just the right grip depth. Packaging had all three heads well-protected, no scuffs.

Installed these on a heavy press assembly and the class 10.9 steel held up perfectly under torque. The hex head gave a solid bite with my socket, and the 90mm length was exactly what I needed.
