M12-1.75 x 30mm 소켓 캡 나사 | 버튼 헤드 육각 소켓 드라이브 | 전체 나사산 | 클래스 10.9 합금강 열처리 블랙 옥사이드 (100개/팩)

The hex socket drive on these M12 screws made installation quick and precise with no cam-out, and the black oxide finish looks clean on my tooling jig. They feel solid enough for heavy-duty use, definitely up to the task for precision assemblies.

Used them to secure a heavy-duty jig on my mill and the hex socket drive made tightening a breeze. All 100 screws had clean threads and consistent length, exactly what I needed.

The thermal black oxide finish on these M12 screws already looks great and seems like it’ll resist rust in my shop longer than the zinc-coated ones I’ve used before. The hex socket drive made tightening them into my jig frame a smooth, no-slip process.
