M12-1.5 x 80mm 육각 머리 볼트 | 클래스 8.8 강철 아연 도금 | 부분 나사산 (50개/팩)

The hex head was a perfect fit for my socket wrench, and the zinc plating on these 80mm screws gives them a solid, corrosion-resistant feel. I used them to secure a heavy-duty bracket, and they threaded in smoothly without any binding.

The partially threaded shaft made all the difference when bolting two thick steel plates together—the thread grabbed cleanly without binding halfway. Zinc coating looks uniform across all fifty pieces, no bare spots or rough edges.

Used these to mount a heavy motor bracket on my workbench, and the hex head made cinching them down with a socket wrench a breeze. The zinc plating still looks clean after a few weeks in a slightly damp shop.
