Countersunk Washer Fluorescent Yellow 50pk

The Countersunk Washer Fluorescent Yellow 50-pack from ALLSTAR PERFORMANCE is designed for mechanics and fabricators who require a reliable visual reference system during engine builds or restorations. These washers are essential for organizing fasteners and preventing reassembly errors in complex projects.

Featuring a countersunk design, these washers sit flush beneath bolt heads, ensuring a clean fit without protrusions that could interfere with engine compartment space or aerodynamic panels. The fluorescent yellow finish enhances visibility, making it easy to identify bolt locations even in low-light conditions.

Ideal for high-performance engine builds and vintage restorations, these washers help track critical torque-to-yield fasteners and distinguish between OEM and aftermarket components. Their durability allows them to withstand the rigors of repeated assembly cycles and exposure to engine temperatures and cleaning solutions.
