M8-1.25 x 12mm 육각 머리 캡 나사 | 클래스 10.9 강철 무도금 | 전체 나사산 (200개/팩)

The threads are clean and consistent across all 200 pieces, and the 12mm length was perfect for my jig assembly. Class 10.9 strength gives me confidence these won't strip under heavy load.

The hex heads sit flush with my socket wrench, and the 10.9 steel threads cut cleanly into the tapped holes every time. I’ve already burned through a third of the box on a frame jig and not a single one has stripped. Exactly what I needed for heavy-duty assembly work.

Came in a 200-count box with uniform threading and crisp hex heads—no burs or loose plating on any of them. The Class 10.9 steel feels solid for our jig assembly, and they thread into M8 holes smoothly without needing extra force.
