براغي رأس سداسي M24-3 × 220 مم | فولاذ عادي فئة 10.9 | ملولبة جزئيًا (5 / عبوة)

The partially threaded design made seating them in the coupling a breeze, and the hex heads grabbed my socket without any slipping. These 220mm lengths feel hefty and solid, exactly what I needed for the frame assembly.

My torque wrench clicked right on spec driving these into a heavy steel frame—the Class 10.9 rating is no joke. The partial threads let me get a solid bite without bottoming out in the blind hole.

I threaded several of these M24-3 x 220mm bolts into a heavy steel frame, and the Class 10.9 steel held up perfectly under full torque without any stripping—solid engineering grade fasteners. The partially threaded shank made alignment easier than a fully threaded bolt.
