M12-1.75 X 60mm 소켓 캡 나사 | 버튼 헤드 헥각 소켓트 드라이브 | 풀 나사산 | 클래스 10.9 합금강 열처리 블랙 옥사이드 (50개/팩)

I needed a solid batch of M12 screws for a precision assembly table, and the black oxide coating on these looks tough and uniform. The hex socket drive seated perfectly without any wobble, and the 60mm length was spot on for my needs.

Installing these on a jig fixture for my mill and the 10.9 alloy steel feels really solid; the button head sits flush enough that nothing snags. The black oxide finish adds a nice level of corrosion resistance for the shop environment.

I’ve been using these for a heavy-duty press fixture and the black oxide finish is holding up great against chips and oils. The hex socket drive makes it easy to get good torque with a standard driver.
