M10-1.5 X 20mm 소켓 캡 스크류 | 플랫 헤드 육각 소켓 드라이브 | 전체 나사산 | 클래스 12.9 합금강 아연 도금 (100개/팩)

Class 12.9 strength gives me confidence using these for heavy jig fixtures—no stripping or head snapping under torque. The zinc plating looks clean and consistent across all 100 pieces in the pack.

The hex socket drive seated perfectly with my Allen key, and the zinc plating gives them a clean, uniform look that resists rust so far. All 100 threads were clean and consistent, which made quick work of my precision assembly setup.

Used these for a jig I'm building and the hex socket drive makes torquing them down precise without worrying about cam-out. The zinc plating looks clean and adds just enough corrosion protection for a workshop environment. Nice upgrade from the usual hardware store stuff.
