M12-1.75 x 200mm 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 나사산 | 강도 등급 12.9 합금강 아연 도금 (10개/팩)

The 200mm length was exactly what I needed for my jig setup, and the zinc plating looks durable enough to resist rust. These M12 screws threaded smoothly into pre-tapped holes without any binding.

The hex socket drove in cleanly with a standard Allen key, no stripped edges or fuss. At 200mm long with that partial thread, they gave me exactly the grip I needed for a tooling fixture. Zinc plating looks uniform too, so they’ll hold up fine on the shelf.

I needed some heavy-duty bolts for a jig I’m building, and these 12.9 alloy steel screws threaded smoothly into the tapped holes without binding. The zinc plating looks clean and even, and the partially threaded design saved me time on alignment.
