Countersunk Washer Blk 1/4in x 3/4in 50pk

The Allstar Performance Countersunk Washer Black 1/4" x 3/4" 50-pack is a precision fastener component engineered for assembly applications requiring flush mounting and a clean finished appearance. These black anodized aluminum washers feature a countersunk profile that allows fastener heads to sit flush with the surface, eliminating protrusions that could interfere with assembly fit, component alignment, or aesthetic requirements. The 50-piece quantity provides sufficient inventory for medium-scale projects or maintenance applications.

The 1/4-inch inner diameter accommodates quarter-inch fasteners, while the 3/4-inch outer diameter distributes load effectively across the mounting surface. At 0.188 inches thick, these washers provide structural support while maintaining a low-profile fit in space-constrained assemblies. The black anodized aluminum construction offers corrosion resistance and a uniform matte finish that resists fingerprints and maintains appearance over extended use. This material choice balances weight savings with durability, making these washers suitable for both indoor applications and outdoor environments where light to moderate exposure occurs.

Users assembling motorsports components, custom mechanical projects, or equipment requiring consistent fastener presentation benefit from the flush-mount design. The countersunk profile is particularly valuable in applications where surface uniformity, aerodynamic cleanliness, or safety (preventing snag points) matters. The 50-pack size fits builders and repair technicians who maintain stock for recurring projects without excessive surplus storage requirements. Each washer is finished to consistent specifications, ensuring repeatable results across multiple assembly stations or build cycles.
