Countersunk Washer Black 50pk

The Countersunk Washer Black 50pk from ALLSTAR PERFORMANCE is an essential fastener component for automotive restoration, body work, and chassis assembly. Designed specifically for engine bay and frame applications where a flush, professional finish is non-negotiable, these countersunk washers sit flush beneath bolt heads to eliminate protrusions that could interfere with panels, wiring, or aerodynamic flow. Whether you're rebuilding a street machine, fabricating a custom frame, or restoring a classic, having a reliable supply of black countersunk washers eliminates downtime and ensures consistent results across multiple fastening points.

Each washer in this 50-pack features a 0.25-inch inner diameter with a 1-inch outer diameter and 0.188-inch thickness, engineering the perfect balance between load distribution and low-profile installation. The black plastic construction resists corrosion and won't degrade under engine heat or UV exposure, making these washers ideal for both underhood and exterior body applications. The countersunk profile allows bolt heads to nest completely flush against mounting surfaces, preventing snags on wiring harnesses, hoses, or adjacent components while maintaining a clean, factory-correct aesthetic that matters in high-end restorations and show builds.

Mechanics, fabricators, and restoration enthusiasts rely on this 50-piece set for comprehensive body and chassis projects where numerous fastening points require uniform treatment. The plastic material eliminates galvanic corrosion risks when fastening aluminum or composite panels, and the black finish remains invisible once installation is complete. Compatible with standard 1/4-inch fasteners, these washers integrate seamlessly into engine dress-up kits, body mount restorations, and custom assembly work where detail and durability drive the final result.
