براغي رأس سداسي M20-2.5 X 130mm | فولاذ فئة 8.8 مطلي بالزنك | ملولبة جزئياً (10 / عبوة)

Installed these bolts to secure a conveyor belt bracket, and the partial threading made alignment much easier than fully threaded ones. The zinc coating looks solid and slipped into the M20 nut without any binding.

Used these to secure a heavy-duty press table at work—the hex head let me really torque them down with a socket wrench without stripping. The zinc coating seems durable enough to resist rust for now, even in a shop that sees some moisture.

The partially threaded design grabbed the bolt perfectly for the steel frame I'm bolting together, and the zinc coating looks clean and even. Class 8.8 held up to my torque wrench without a hint of stripping. The hex head sat flush in my socket, so no slippage at all.
