M20-1.5 X 150mm 外六角螺絲 | Class 8.8 鋼 普通 | 部分螺紋 (10個/包)

Needed these for a heavy-duty machine base, and the hex head allowed my socket to grip without slipping. The threading is clean and the 8.8 steel feels solid for the price.

The partially threaded design made aligning the bolt through my equipment frame much easier than with fully threaded ones. These class 8.8 steel bolts tightened down firmly with no stripping or give.

Had to tighten down some heavy equipment mounts and these M20 bolts handled the torque beautifully, the hex head gave my socket wrench a solid grip. Just the right length at 150mm for what I needed, and the partial threading made alignment easier than with fully threaded ones.
