HOLO-KROME 72066 #8-32 X 1-1/4" 소켓 캡 나사 | 육각 소켓 드라이브 | 합금강 열처리 블랙 옥사이드 (100 / 패키지)

The black oxide finish on these #8-32s looks even better in person, and the hex socket drive seated perfectly with my Allen key on the first try. I’ve used about forty of them on a tooling fixture so far, not a single stripped head or cross-threaded hole.

I needed some heavy-duty screws for a jig I was building, and these #8-32 socket caps fit perfectly. The hex drive made it easy to apply torque without stripping the head, and the black oxide coating gives them a nice, uniform look.

The black oxide finish looks sharp and has held up well during assembly on my jig fixture, no flaking or rust. Threads started cleanly by hand every time, and the hex socket drive seated perfectly with a standard Allen key. These are going to be my go-to for precision work.
