Countersunk Washer Blue 50pk

The Allstar Performance Countersunk Washer Blue 50-pack (SKU ALL18693-50) is an essential fastening solution for mechanical assembly, restoration, and motorsports applications. This pack is ideal for technicians, restoration shops, and operators who require reliable fastening hardware across multiple projects without frequent reordering.

Engineered with a 0.188-inch inner diameter and 1-inch outer diameter, these countersunk washers effectively distribute fastener load across a wider surface area while maintaining a recessed profile that sits flush with component surfaces. Each washer measures 0.188 inches thick and is constructed from durable plastic material in a blue finish for easy identification and inventory tracking.

Technicians restoring classic vehicles, rebuilding engines, or assembling tactical equipment will benefit from these bulk fastener packs that standardize hardware across multiple builds. The countersunk design allows fasteners to seat smoothly without protruding edges, preventing snagging and ensuring a clean surface fitment. This geometry is standard across automotive, aircraft, and precision mechanical assembly work where load distribution directly impacts structural integrity and longevity.
