براغي رأس سداسي M20-2.5 × 70 مم | فئة 10.9 فولاذ أصفر زنك | ملولبة بالكامل (20 / عبوة)

These hex bolts were exactly the right length for mounting a heavy motor base. The yellow zinc coating looks uniform and tough, and the hex heads gave my socket a solid bite.

I needed some beefy bolts for a press jig I'm building, and these M20s threaded in smooth and snug without any binding. The hex head caught my 10mm socket perfectly, which made torquing them down a breeze.

The hex heads seated perfectly in my socket without any rounding, and the yellow zinc coating looks uniform across all 20 pieces. Threads are clean and the 10.9 steel feels plenty rigid for what I’m bolting together.
