M12-1.5 X 130mm 육각 머리 캡 나사 | 클래스 8.8 강철 아연 도금 | 부분 나사산 (25개/팩)

Installing these on a heavy-duty jig I built, the partial threading made alignment much easier than fully threaded bolts I've used before. The hex head grabbed the socket cleanly and the zinc coating looks durable. Solid fasteners for the price.

Had to torque these down pretty hard on some equipment mounts, and the hex head held up perfectly without stripping. The partially threaded design gives just the right amount of grip where you need it.

Used these to mount a heavy steel bracket to a concrete wall, and the Class 8.8 strength handled the torque perfectly. The zinc plating on the heads still looks clean after a week exposed to light moisture.
