M16-2 x 160mm 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 나사산 | 클래스 12.9 합금강 열처리 블랙 옥사이드 (10개/팩)

I needed a set of high-strength bolts for a heavy-duty jig, and these 12.9 alloy steel screws fit perfectly. The hex socket drive made installation smooth, and the partially threaded design worked great for clamping.

I needed long, heavy-duty fasteners for a custom jig build, and these 160mm socket cap screws with the black oxide finish fit the bill perfectly. The partially threaded design seated cleanly, and all ten pieces had crisp, burr-free threads.

Machined a new fixture plate this weekend and these M16 socket caps seated perfectly in the counterbores—the black oxide finish gave them a nice uniform look against the steel. Threads were clean and the hex drive bit grabbed without any wobble.
