The Pro-Bolt Countersunk Alloy Washer is designed for automotive and motorcycle enthusiasts looking to achieve a refined, lightweight finish for non-critical bodywork and fairing components. These washers effectively distribute bolt pressure to prevent surface damage and pull-through, offering a significant weight reduction compared to steel or titanium alternatives. Please note that these components are strictly for non-safety critical applications and must never be utilized in high-stress or structural mounting points.

No. These washers are strictly for non-safety critical areas and must never be used on brake, suspension, or engine mounting points.
It refers to a high-strength aluminium alloy that has undergone specific heat treatments to maximize its performance and durability.
Sizes are indicated by thread diameter followed by outer diameter. Measure your existing bolt thread and the required clearance for your mounting hole.
They are highly resistant to saltwater and road film, but they should be kept clean to maintain the integrity of the anodised layer.
Yes, they are compatible with countersunk steel bolts, though they are often paired with Pro-Bolt aluminium bolts for a weight-matched setup.
Verify that you are using a countersunk head bolt that matches the washer angle and that the hole has been correctly prepared for countersinking.
Ensure your tools are correctly sized for the bolt head and use a protective layer on the tool if necessary to prevent direct metal-on-anodised contact.
To ensure proper installation, match the washer size (thread diameter x outer diameter) exactly to your existing bolt hardware. When tightening, apply moderate pressure; avoid over-torquing, as aluminium is softer than steel and can deform if forced. Because these parts are anodised, use high-quality hex tools that fit snugly to avoid marring the surface coating. Cleaning is straightforward: use a soft cloth with mild soapy water to remove road film. Avoid harsh chemical cleaners or abrasive brushes that could strip the anodised layer over time. Always confirm that your chosen mounting point is not subjected to chassis or engine stress before installation.
