M18-1.5 X 75mm 外六角螺絲 | 10.9 級碳鋼 普通 | 部分螺紋 (100 個/包)

Threads seated cleanly in an M18 tapped hole on my jig table and the 10.9 steel took a full torque without stripping a single one. The partial threading made alignment a lot easier on thick flanges.

All one hundred came out of the box with clean threads and no burrs, and the 75mm length with partial threading seated perfectly in my jig setup. The class 10.9 steel feels seriously tough, and I didn’t strip a single one torquing them down with a socket drive.

The hex head design made it easy to get a solid grip with my socket wrench during assembly. These 10.9 steel screws feel sturdy and reliable, with the partial threading working exactly as needed for my project.
