M30-3.5 x 130mm 육각 헤드 캡 나사 | 클래스 10.9 강철 아연 도금 | 부분 나사산 (15개/팩)

The zinc plating looks even and clean, and the class 10.9 rating gives me confidence they won't shear under load. Threads engaged smoothly into our fixture plate without any binding, and the partial threading made alignment a lot easier. Already ordered another pack for the next job.

These threading is clean and the zinc coat looks even, so they'll hold up fine in a damp shop. The partial threads on the 130mm length give good grip without bottoming out, and the hex heads took a socket wrench without stripping.

I needed heavy-duty bolts for mounting a press, and these class 10.9 hex heads handled the torque without any thread stripping. The zinc plating gave them a clean, uniform look that should resist rust in my workshop.
