Specially designed countersunk aluminum washers allow socket head fasteners to install flush with the surface, creating a smooth finished look. Use when mounting roofs, side skirts and spoilers or replacing sharp edged fasteners inside the cockpit.
A flush-mounted fastener is only as good as the surface supporting it. Allstar Performance Countersunk Washers provide a precision seating surface that helps flat head fasteners clamp securely while distributing load more evenly across the mounting material.
The result is a cleaner installation, improved fastener support, and a professional finish that's built to withstand demanding automotive environments. Whether assembling body panels, interior components, floor pans, or custom fabricated parts, these durable washers deliver the strength, precision, and appearance serious builders demand.
