براغي رأس سداسية M42-4.5 × 300 مم | فولاذ درجة 10.9 غير معالج | خيط جزئي (1 / عبوة)

The partially threaded design made it easy to start by hand before tightening with a socket, and the 300mm length was perfect for a custom jig I’m building. Class 10.9 steel gives me confidence it’ll hold up under heavy loads.

I needed a robust bolt for a heavy press rebuild, and these 300mm long class 10.9 hex heads torqued up perfectly without any thread binding. The plain steel finish feels sturdy and the drive fit was snug in my socket.

The partially threaded design on these M42 bolts grabbed perfectly when I was mounting a heavy jig to the workbench. They tightened up solidly with just a standard socket wrench.
