Installation Notes
Use a suitable thread-locking compound, such as Loctite, to help secure the hardware during installation. Follow the helmet and accessory manufacturers' installation instructions.
Important: Verify the required bolt length for your specific helmet, retention system, and side rail configuration before purchasing. Some helmet shells are thicker than others, and the 20 mm extended-length bolts may not provide sufficient length for every setup.
