Under pressure, this washer expands to create a permanent, weatherproof seal—ideal for outdoor applications where moisture resistance is crucial. The screws are zinc plated and finished with an 'Elementech' coating, providing superior corrosion resistance. This coating has been rigorously tested, passing salt spray testing for up to 1,000 hours, ensuring long-lasting durability in harsh conditions.
