M8-1.25 X 170mm 육각 헤드 캡 나사 | 8.8급 강철 아연 도금 | 부분 나사산 (25개/팩)

The zinc plating on these M8 screws looks clean and the hex head grips well with a socket. I used them to secure a heavy piece of equipment and the partially threaded design made installation simpler than expected.

I paired these with some standard M8 nuts for a heavy-duty shelf bracket, and the 170mm length gave me just the right amount of bite through the wood and into the stud. The zinc plating seems consistent and didn't flake off as I turned them with a socket.

The partial threading on these M8 bolts made aligning them in tight spots so much easier. I used a socket driver and the hex head grabbed perfectly without slipping. Solid purchase for the price.
