M8-1.25 x 35mm 소켓 캡 나사 | 육각 소켓 드라이브 | 풀 스레드 | 클래스 12.9 합금강 열처리 블랙 옥사이드 (200개/팩)

Perfect thread engagement every single time I've used them, and the hex socket drive bites firmly without any stripping. The thermal black oxide finish has held up great across multiple assemblies so far. For 200 pieces at this price, these are a solid buy for any jig or fixture work.

The black oxide finish on these M8 screws gives them a clean, professional look for jig builds. They threaded smoothly into my aluminum fixture without any binding, and the 12.9 alloy steel feels incredibly sturdy for the price per pack.

The hex socket drive on these screws fits my Allen key perfectly, and the black oxide finish looks clean on our jig setup. They threaded smoothly into tapped holes without any binding, which saved me time on a recent machining project.
