The ALLSTAR PERFORMANCE Countersunk Washer #10 10-pack (SKU ALL 18660) is a precision fastener component engineered for aerospace, automotive, and industrial assembly applications where flush mounting and clean aesthetics are critical. Each pack contains ten aluminum countersunk washers rated for #10 holes with a 1-inch outer diameter and 0.188-inch thickness, delivering consistent performance across high-volume production runs and professional repair work.
The countersunk design allows fastener heads to sit flush with the mounting surface, eliminating protruding edges that could interfere with aerodynamic flow, create snag points, or compromise component fit. The aluminum construction offers lightweight characteristics ideal for weight-sensitive applications while maintaining structural integrity under vibration and thermal cycling. The 0.188-inch thickness provides adequate bearing surface to distribute load without excessive material waste, and the natural aluminum finish allows direct integration into anodized or painted assemblies without compatibility concerns.
This ten-piece countersunk washer set is purpose-built for professionals who depend on standardized fastener components across multiple assembly stations or maintenance tasks. Racing teams, aircraft maintenance shops, and automotive fabricators rely on ALLSTAR PERFORMANCE hardware for its dimensional consistency and repeatability. The 10-pack format suits both repair scenarios requiring individual replacement washers and production environments needing bulk stock for scheduled assembly work.
ALLSTAR PERFORMANCE is recognized across automotive racing and restoration sectors for producing OEM-compatible fastener components that meet or exceed industry specifications. Countersunk washers of this type conform to standard fastener dimensions that ensure drop-in compatibility with #10 countersunk screws and bolts across equipment from different manufacturers, reducing inventory complexity and streamlining procurement for shops managing diverse equipment.
