The Pro-Bolt Countersunk Alloy Washers are designed for automotive and motorcycle enthusiasts looking to reduce weight while adding a clean, finished look to their non-critical mounting points. These lightweight aluminum washers effectively distribute load for countersunk bolts, preventing them from damaging mounting surfaces. Please note that due to their material composition, they are strictly intended for non-safety critical applications and should not be used in high-stress areas like engine mounts or braking systems.

No. These washers are for non-safety critical applications only and should never be used on brakes, suspension, or engine components.
You can achieve a weight reduction of up to 60% compared to traditional stainless steel or titanium washers.
No, they are made from aluminum alloy and are non-magnetic.
The 8-12 micron anodization is highly durable and resistant to environmental exposure, though extreme long-term UV exposure can affect any colorant over many years.
The M6 refers to the bolt thread diameter, and the 19mm refers to the outer diameter of the washer.
You are applying too much torque. Aluminum is soft; tighten until snug only.
Ensure your tools are clean and that you are using the correct socket or driver size to avoid tool slip.
To install, ensure the hole diameter is matched to your specific washer size. Place the washer onto the countersunk bolt before threading it into your mounting point. Because aluminum is softer than steel, avoid overtightening to prevent stripping the threads or deforming the washer. These washers are intended for hand-tightening or low-torque fastening; avoid using high-powered impact drivers. Clean with mild soap and water using a soft cloth; avoid abrasive cleaners or wire brushes that could scratch the anodized layer and expose the bare metal to corrosion.
