M16-1.5 X 75mm 육각 머리 볼트 | 클래스 8.8 강철 아연 도금 | 부분 나사산 (25개/팩)

The partial threading on these hex bolts made all the difference when I needed to secure a thick steel bracket without the threads binding up. They tightened down smoothly with a standard socket, and the zinc finish hasn't shown any rust after a month in the garage.

The zinc plating is holding up nicely even with constant wrench work, and the partial threads grabbed cleanly on the first pass. These hex heads sit flush with standard sockets, so installation was a breeze for my equipment frame.

I needed M16-1.5 x 75mm bolts for a trailer hitch repair, and the partially threaded design gave me perfect grip where I needed it. The zinc plating seems solid and the hex heads fit my socket wrench without any stripping.
