براغي رأس سداسي M33-3.5 × 140 مم | فئة 8.8 فولاذ عادي | ملولبة بالكامل (3 / عبوة)

Threading went smooth all the way with these fully threaded screws — no binding. The hex head grabbed nicely with a 46mm socket, and they held a heavy bracket steady on the first try. Exactly what I needed for a solid machine mount.

Used a 140mm hex head bolt to fasten a heavy bracket to a steel beam, and the 8.8 steel held up perfectly to tightening. The fully threaded design gave me good grip through the entire depth of the joint.

The threads on these are sharp and consistent all the way to the head, which made starting them in a tight flange a breeze. For the price of a three-pack, you get solid Class 8.8 steel that's clearly meant for real torque.
