1-1/4-12 X 10" 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 나사산 | 합금강 열처리 블랙 옥사이드

The partially threaded design made these perfect for my jig assembly where I needed precise clamping without fighting threads the whole length. The hex socket drive takes an Allen wrench easily, and the black oxide finish already looks like it’ll resist shop grime well.

The black oxide finish on these screws is spot-on, and the 10" length gave me just the right reach for a stubborn jig setup. They threaded in clean and held tight under load, exactly what I needed for the tooling assembly.

I had to swap out a stripped bolt on a milling machine fixture, and these socket cap screws fit the 1 1/4-12 threads perfectly. The black oxide coating gives them a nice, uniform look that should resist rust in the shop environment.
