M6-1 x 45mm 外六角螺絲 | 10.9 級碳鋼原色 | 半牙 (300 顆/包)

I needed these for a machinery repair and the partially threaded design made alignment much easier than fully threaded bolts I've used before. They fit perfectly with a standard socket, and the 300-count package means I have plenty left for future projects.

Finally found M6 hex bolts with the partial threading I needed for a tight assembly, and the 10.9 steel feels much tougher than the standard grade I used to buy. The 45mm length was spot on for my application, and the hex head seated perfectly with a socket wrench.

The partial threads on these M6 screws made lining up the components on our assembly jig much easier than fully threaded bolts would have. Driving them in with a socket wrench was smooth and they held torque perfectly.
