The Pro-Bolt Countersunk Alloy Washers are designed for automotive enthusiasts and hobbyists looking to enhance their vehicle's aesthetics while ensuring secure fastening in non-safety critical applications. These lightweight, anodized aluminum washers distribute the load of countersunk bolts to prevent pull-through and damage to components. While they offer superior corrosion resistance and a sleek black finish, they are not intended for use in high-stress or critical load-bearing areas.

No. These washers are made of aluminum and are strictly intended for non-safety critical applications; they should never be used on brakes, suspension, or engine internals.
Each pack contains 5 pieces.
The 8 to 12-micron anodized coating provides essential protection against corrosion, saltwater, and road grime while providing a durable, high-quality black finish.
No, they are specifically engineered for use with countersunk head bolts.
Aluminum is chosen primarily for its significant weight savings, being 60% lighter than stainless steel, making it ideal for cosmetic weight reduction.
Verify that the bolt head is fully seated in the countersunk profile of the washer and that the mounting surface is flat.
Ensure the bolt head is clean before installation and avoid using hard metal tools directly against the anodized finish during tightening.
To ensure the best performance, match these washers specifically with countersunk bolts of the correct diameter. When installing, place the washer between the bolt head and the surface, ensuring the countersink angle aligns perfectly with the washer geometry.
Care instructions involve keeping the anodized finish free from harsh abrasive cleaners that could scratch the surface. If cleaning the vehicle, standard mild automotive soap is sufficient to maintain the finish. Avoid overtightening, as aluminum is prone to thread stripping if subjected to excessive torque; use only the torque specification required for the specific fastener, which should be lower than what you would use for steel bolts.
