M12-1.25 X 65mm 육각 머리 캡 나사 | 클래스 8.8 강철 아연 도금 | 부분 나사산 (50개/팩)

The zinc plating on these looks even and clean, no flaking or rough spots out of the bag. The partial threading gives just the right grip for my jig setup, and the hex heads seated perfectly in my socket without any wobble.

I needed some strong bolts for a trailer repair, and these hex heads worked perfectly with my socket wrench. The zinc plating looks solid and should hold up fine outdoors.

The partial threading was a big reason I picked these, and it saved me a ton of time on a bracket install where I needed the plain shank to align the plates. The 8.8 steel feels solid in the hand, and every one of the 50 cleaned up a threaded hole without binding.
