M24-3 x 60mm 소켓 캡 나사 | 육각 소켓 드라이브 | 풀 나사산 | 클래스 12.9 합금강 열처리 블랙 옥사이드 (10개/팩)

I needed some high-strength fasteners for a precision assembly, and these M24-3 x 60mm socket cap screws fit perfectly. The hex socket drive made installation straightforward, and the black oxide finish looks great. They feel solid and well-made.

Installed these in a custom jig for a heavy-duty press; the black oxide finish held up perfectly against a few light oil sprays. The hex socket didn't strip even with a high-torque driver, which is exactly what I needed for precision work.

These bolts threaded smoothly into my jig fixture without any binding, and the 12.9 grade gives me confidence they'll handle the clamping force. The black oxide finish looks clean and professional against the steel.
