M8-1.25 X 25mm 소켓 캡 나사 | 버튼 헤드 육각 소켓 드라이브 | 풀 나사산 | 클래스 12.9 합금강 아연 도금 (200개/팩)

Installed these on a jig I was building, and the 12.9 alloy steel feels noticeably stronger than the regular screws I used before. The zinc plating has a consistent, smooth finish that didn't flake when I torqued them down.

I was honestly surprised by how perfectly these fit into my jig—the hex socket drive grabbed cleanly with no stripping, and the Class 12.9 alloy steel feels rock solid under torque. Finished a whole fixture assembly with the box of 200 and haven't had a single dud in the batch.

The hex socket drive sits perfectly flush, and every single screw threads in cleanly without any wobble or burrs. I've used a dozen already on a jig fixture and they hold tight at full torque, so this pack should last me through a ton of builds.
