براغي رأس سداسية مقاس M36-4 × 80 مم | فولاذ فئة 10.9 عادي | ملولبة بالكامل (15 / عبوة)

Threaded cleanly into our jig without any binding, and the hex head held up perfectly under a high-torque driver. Definitely solid for repeated assembly work.

Torqued these down to spec on our press frame and the Class 10.9 steel held up without a hint of stretching. The fully threaded length made alignment a breeze through the flange, and the hex heads grabbed a socket cleanly every time. Exactly what I needed for heavy equipment.

Put my new lathe back together with these bolts and the hex heads gave the socket a nice solid bite. The 80mm length was just right for the heavy flange I was securing.
