براغي رأس سداسي M36-4 × 190 مم | فئة 10.9 فولاذ عادي | ملولبة جزئيًا (1 / عبوة)

The partially threaded section made seating them in our press frame a breeze, and the hex head gave my impact wrench plenty of bite. These 10.9s have held up through a week of heavy vibration without a hint of loosening.

I had to use a breaker bar to get these torqued properly, but once seated they held our assembly together with zero play. The hex head on the Class 10.9 steel gave a solid socket grip without rounding.

The threads are sharp and clean, so the nut threaded on smoothly without any binding. Used these to bolt a heavy press frame together, and the 190mm length gave perfect clearance for the assembly. Exactly the grade 10.9 strength I needed for the load.
