براغي رأس سداسي M20-2.5 × 130 مم | فولاذ فئة 10.9 عادي | ملولبة جزئيًا (10/عبوة)

The partially threaded shaft on these M20-2.5 screws made it easy to align the machinery bracket without fighting the threads. They tightened up solidly with a socket, and the Class 10.9 steel feels tough enough for the job.

I needed heavy-duty screws for my tractor's hitch attachment, and the Class 10.9 steel really delivers—no bending under torque. The partially threaded design let me get a solid grip without stripping.

These bolts felt substantial right out of the package and seated perfectly in my jig fixture. The 130mm length was exactly what I needed for a thick assembly, and the partially threaded section held tight under torque.
