براغي رأس سداسي M42-4.5 × 260 مم | فولاذ فئة 10.9 عادي | ملولبة جزئيًا (1/عبوة)

Longer than my forearm and built like a tank—the partially threaded section made seating them in our press frame much easier than I expected. Wrenched them down with a socket and they took the torque without a hint of flex.

These are absolute monsters at 260mm long, but the M42 thread cut perfectly and the partially threaded section gave me plenty of grip for a heavy equipment frame. The hex head took a socket without any stripping, and the 10.9 steel feels rock solid.

The partially threaded design made alignment a breeze when I torqued these into the equipment frame—the 10.9 steel took the load without a hint of flex. Threads cut clean and the hex head seated perfectly with my socket.
