براغي رأس سداسي M30-3.5 × 400 مم | فئة 10.9 فولاذ عادي | ملولب جزئيًا (1/عبوة)

Installed these on a heavy conveyor frame, and the class 10.9 steel handled the torque without any flex. The partially threaded section made alignment much easier than fully threaded bolts.

The hex head grabs a socket wrench perfectly, and the 10.9 steel feels rock solid when torqued down on our press frame. Partially threaded design gave me just the right grip length for the flange setup.

I needed a heavy-duty fastener for a press, and the 400mm length on these M30 hex head screws gave me plenty of thread engagement. The hex head held my impact socket perfectly without slipping.
