براغي رأس سداسية M36-4 × 210 مم | فولاذ درجة 10.9 عادي | ملولبة جزئيًا (1 / عبوة)

I needed a heavy-duty fastener for a piece of industrial machinery, and the 210mm length on these class 10.9 steel screws fit perfectly. The hex head gave my socket wrench a solid grip without any slipping during installation.

The partially threaded design made it easy to get a secure hold during assembly. These screws feel solid and well-made for heavy-duty use.

The hex head on these cap screws grabbed my socket wrench perfectly without slipping, and the 210mm length was exactly what I needed for that machinery alignment job. The partially threaded design made installation much smoother than fully threaded bolts I've used before.
