M16-2 X 110mm 소켓 캡 나사 | 육각 구동 | 부분 나사산 | 클래스 12.9 합금강 아연 도금 (25 / 팩)

The partially threaded design makes them easy to align in my press tooling, and the zinc finish resists rust nicely. They tightened smoothly with my hex key, no stripping at all.

I've been using these in a custom jig I built for my workshop and the hex socket drive made installation quick even in tight spaces. The zinc plating has held up well against minor rust during a couple weeks in my damp garage.

The partially threaded design on these M16-2 screws made aligning them in my jig setup much easier than fully threaded ones. They feel solid and the zinc plating looks clean, held up well after a few rounds of tightening and loosening. Exactly what I needed for a sturdy tooling fixture.
