Allstar Performance Countersunk Washer Black #10 10pk ALL18661

Countersunk washers are essential for creating clean, flush fastener installations where fasthead profile matters—especially in visible engine bays, chassis work, and aerodynamic components. These Allstar Performance washers eliminate gaps between fasteners and mounting surfaces, providing a professional finish while distributing load more effectively than standard washers. The black anodized aluminum construction resists corrosion and matches modern engine dress-up, making them ideal for both competition and street applications.
