M8-1.25 x 60mm 소켓 캡 나사 | 버튼 머리 육각 소켓 드라이브 | 전체 나사산 | 합금강 12.9등급 아연 도금 (100개/팩)

Put these on a heavy-duty press brake die holder I’m building, and the Class 12.9 alloy steel makes them feel rock solid under torque. The hex socket drive engaged cleanly without any stripping. Exactly what I needed for precision tooling.

Used these for fixturing a custom jig on my mill table, and the 60mm length was just right for the stack-up. The zinc plating on the 12.9 alloy steel looks clean and seems robust enough to hold up in a shop environment. Torqued them down without any stripping or cam-out issues.

The hex socket drive made installation a breeze with my Allen wrench, and the zinc plating on these 12.9 alloy steel screws looks flawless. They feel incredibly sturdy for my press tool jig, a solid upgrade from standard hardware.
