براغي رأس سداسي M16-2 × 200 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة جزئيًا (10/عبوة)

Used these to mount a heavy motor bracket, and the hex head let me torque them down securely with a socket. The zinc plating looks clean and the threading feels precise.

The partially threaded design makes seating them in thick flanges much easier than fully threaded bolts. Zinc coating looks even and they torqued down to spec without any deformation.

I was a bit worried about stripping the hex head, but the zinc plating gives it enough grip for a firm socket fit even after a few torques. The 8.8 steel feels solid for a 200mm bolt, and the partial thread worked perfectly for the spacer stack I was assembling.
