M20-2.5 X 320mm 육각 머리 볼트 | 클래스 8.8 강재 무도금 | 부분 나사산 (16개/팩)

The hex head on these M20 screws gives my socket wrench a firm, slip-free grip, and the partially threaded shaft made installing them into the equipment frame quick and easy. Exactly what I needed for a solid, industrial-strength fastening job.

The partially threaded design made alignment a breeze when I was bolting down a steel frame—no fighting with the threads on the first few turns. The hex head sits perfectly in a standard socket, and the class 8.8 steel feels solid without any flex.

Installing these on a heavy press machine and the partial thread made alignment so much easier. The 8.8 steel feels properly hardened, and they torqued down smoothly without any binding.
