M42-4.5 x 190mm 육각 머리 캡 나사 | 클래스 10.9 강재 무도금 | 부분 나사산 (1개/팩)

The hex head is machined precisely—my socket wrench grabbed it without any wobble. The 190mm length was perfect for securing the heavy bracket to the machinery frame. Strong little bolt for the price.

Thread pitch is clean and the hex head grabs a socket without any wobble, which matters when you're torquing these down. The 190mm length gave me just enough reach for the flange assembly I was working on. Solid buy for the price.

These things are solid, the 190mm length gives you plenty of grip, and the partially threaded design made alignment a lot easier on our assembly jig. Exactly what I needed for bolting down some heavy equipment.
