3/4-10 x 2" 소켓 캡 나사 | 육각 소켓 드라이브 | 미국산 | 합금강 열처리 블랙 옥사이드 (25 / 팩)

Installed these in a heavy-duty jig and the black oxide finish held up perfectly against the cutting fluid. The hex socket drive made torquing them down much easier than a standard hex head.

I've been using these socket cap screws for jig building, and the hex socket drive really lets you torque them down tight without stripping. The threads cut cleanly and consistently through the metal every time.

The black oxide finish gives these a nice, uniform look, and every one of the 25 screws in the pack threaded cleanly into my jig without any binding. The hex socket drive is tight and precise, exactly what you need for machinery work where you don't want a stripped head.
