براغي رأس سداسي M20-2.5 X 210mm | فولاذ فئة 10.9 مطلي بالزنك | سنون جزئية (10 / Pkg.)

I used these for mounting a heavy gearbox, and the hex heads let me torque them down properly with a socket. The zinc coating looks clean and seems like it will resist rust in the shop.

The partial threading on these M20 bolts makes them perfect for clamping thick steel plates without bottoming out. For the price, the zinc coating looks even and clean, and they threaded smoothly into my existing tapped holes without any binding.

Wrench slid right on and the hex head grabbed cleanly without rounding, exactly what I need for the heavy machine jig I'm bolting together. Class 10.9 steel feels rock solid, and the zinc plating survived a bit of shop grime without any rust spots.
