Countersunk Washer Fluorescent Yellow 50pk

The Countersunk Washer Fluorescent Yellow 50-pack from ALLSTAR PERFORMANCE is a practical fastening solution designed for applications where visibility and organization matter. With a 0.25-inch inner diameter, 1-inch outer diameter, and 0.188-inch thickness, these neon yellow plastic washers deliver reliable load distribution across a range of assembly and maintenance tasks in automotive, recreational, and industrial settings.

The countersunk design allows fasteners to sit flush with surfaces, creating a clean finish while maintaining structural integrity. The fluorescent yellow color serves a dual purpose—immediate visual identification of fastened components and enhanced visibility during assembly and disassembly in low-light conditions or cluttered work areas. As plastic washers, they resist corrosion and are non-conductive, making them suitable for electrical applications, sealed assemblies, and environments where metal corrosion is a concern. The 50-unit quantity ensures adequate stock for projects, repairs, or preventive maintenance without frequent reordering.

This product is ideal for engine builders, restoration specialists, recreational vehicle owners, and maintenance technicians who value organization and traceability in their work. Hunters and outdoor enthusiasts working on firearms, equipment modifications, or camp infrastructure benefit from the high-visibility design when managing hardware in field conditions or workshop environments. The compact 50-pack—weighing just 0.24 pounds—fits easily in toolboxes or shop drawers.

ALLSTAR PERFORMANCE has built a reputation in the performance automotive and motorsports community for dependable fastening components. Countersunk washers like these are foundational inventory items for anyone performing regular assembly, repair, or customization work where precision fastening and long-term reliability are required.
