براغي رأس سداسي M24-3 × 40 مم | فولاد فئة 10.9 عادي | ملولبة بالكامل (10 / عبوة)

The hex head grips perfectly with my socket, and the 40mm length was just right for bolting a heavy bracket to a steel frame. These 10.9 grade screws feel solid—no stripping even under a lot of torque. A straightforward, reliable fix for industrial work.

Installed these on a conveyor drive pulley—the hex head gave a solid bite with a 19mm socket, and the full threading held torque evenly across the joint. The 10.9 steel feels plenty tough for the application, and the 40mm length was just right for the flange thickness I was working with.

Packed these into a heavy press fixture, and the hex head grabbed the socket perfectly without any wobble. The 10.9 grade feels solid enough for daily industrial use.
