M8-1.25 x 60mm 소켓 캡 나사 | 버튼 헤드 육각 소켓 드라이브 | 풀 스레드 | 10.9급 합금강 열처리 블랙 옥사이드 (100개/팩)

Had to replace some worn screws on a production fixture, and these button heads seated perfectly with the hex driver. The black oxide finish looks clean and the 10.9 grade gives me confidence they'll hold up under load.

Put a new tooling jig together with these and the hex socket drive made installation a breeze. The fully threaded length gave me plenty of grip for a solid hold. Exactly what I needed for heavy-duty assembly work.

The black oxide finish on these M8 screws looks professional and resists corrosion well, and the hex socket drive made installation with my allen key effortless. They fit perfectly in my jig setup and feel dense and solid, just what I needed for a heavy-duty fixture.
