FAQs
Are these washers safe for structural use?
No. These are for non-safety critical areas only and should not be used in high-stress applications.
What does the anodising thickness mean?
The 8-12 micron layer provides the colour and serves as a protective barrier against corrosion, road film, and saltwater.
Can I use these with M6 bolts?
No, these are specifically designed for 5mm thread diameters.
How many washers are in a pack?
Each pack contains five individual washers.
Will they rust like steel washers?
They are highly resistant to saltwater and road film thanks to the anodisation process, but they should be kept clean to maintain the finish.
Troubleshooting
Washer is deforming during installation
You are likely applying too much torque. Aluminium is a softer metal than steel; tighten only until snug.
Bolt head is not sitting flush
Verify the bolt type matches the countersink angle of the washer and ensure there is no debris between the washer and the mounting hole.

Setup, Compatibility & Care
To install, simply place the washer between the countersunk bolt head and the panel surface before tightening. Ensure the washer is seated squarely to allow the bolt head to sit flush. Since these are made from aluminium, always tighten by hand to avoid stripping the threads or deforming the washer. Avoid using aggressive chemicals or harsh solvents when cleaning to preserve the integrity of the 8-12 micron anodised coating. If the surface becomes dull over time, a mild soap and water solution is sufficient for maintenance.
