براغي رأس سداسي M16-2 × 75 مم | فولاذ كلاس 8.8 زنك أصفر | ملولبة جزئيًا (25 / عبوة)

These held up perfectly under a heavy vibration load on our conveyor frame, no loosening at all. The yellow zinc finish is a nice touch for shops where rust is always a worry. Probably the best value I've found for Class 8.8 hardware in this size.

The hex head gave my socket wrench a solid bite without slipping, and the yellow zinc finish looks more durable than plain steel. Installed a dozen into a heavy equipment frame without a single cross-thread.

These bolts threaded perfectly into my jig's tapped holes without binding, and the hex head let me torque them down securely with a socket. The yellow zinc coating looks clean and should resist rust well in my shop.
