1-14 x 6-1/2" 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 나사산 | 합금강 열처리 블랙 옥사이드 (5 / 패키지)

The partially threaded shank made all the difference when I needed to secure a heavy jig fixture—no wasted threads binding up in the workpiece. They tightened down evenly with a hex key and the thermal black oxide seems like it'll hold up in my shop's oily environment.

The black oxide finish on these 1-14 socket cap screws looks sharp and held up fine during assembly on my jig. This length is hard to find locally, so I’m glad the packaging arrived intact and the threads were clean right out of the bag. Exactly what I needed for a deep fixture I’m building.

The partially threaded design made these screws easy to tighten into my jig setup without any slipping, and the black oxide finish gives them a solid, professional look.
