M10-1.5 x 110mm 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 스레드 | 클래스 12.9 합금강 열처리 블랙 옥사이드 (50개/팩)

The black oxide finish wiped clean with a rag and hasn't shown a hint of rust after a week of oily shop use. The 12.9 hardness is the real deal—they've held torque on a jig I built without any thread stretch. Half the price of what the local fastener shop wanted, and the partial thread makes alignme

I needed a longer shoulder screw for a custom jig, and the 110mm length with a partially threaded shank was exactly what I was looking for. Installation was smooth with a hex key, and a quick check confirmed they’re pulling tight without any stripping.

The black oxide finish on these screws held up perfectly during assembly, even with a lot of handling. They threaded cleanly into my tooling jig without any binding, and the 110mm length was exactly what I needed.
