M8-1.25 x 240mm 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 스레드 | 클래스 12.9 합금강 열처리 블랙 옥사이드 (50개/팩)

These 240mm screws are perfect for a heavy clamping fixture I built; the hex socket drive made torquing them down easy even in tight spaces. The black oxide finish looks clean and seems durable so far.

I needed long M8 bolts for a custom jig, and these 240mm screws reached perfectly through thick aluminum plates. The hex socket drive makes them easy to tighten without stripping, and the black oxide finish looks clean. Worked great for the precision assembly I was building.

The threading on these is clean and consistent—every one of the 50 seated perfectly in my jig without any binding. The black oxide finish is evenly applied and has held up well against shop oil and handling. I’ll be ordering these again for future precision assembly work.
