M36-4 X 100mm 六角頭螺絲 | 10.9級鋼本色 | 全螺紋 (15 個/包)

The threading is perfectly clean all the way down, so they seated without any binding. I torqued them to spec on a heavy press frame and the 10.9 steel held up without a hint of stretch. A solid, no-nonsense fastener for the price.

Needed a set of strong bolts for a custom jig I'm building, and these M36 x 100mm class 10.9 screws are total overkill in the best way. The hex head grabbed my socket perfectly, and the full threading made alignment a breeze.

Installing these on a heavy press, the fully threaded length let me get perfect tension without any extra washers. The hex head grabbed nicely with a socket, and all fifteen bolts had clean, burr-free threads.
