Value Collection R52001051 Fender Flat Washer 18-8 Ss

Product Description

The VALUE COLLECTION R52001051 is a fender flat washer designed for use with 1/4-inch screws and fasteners. Manufactured from Grade 18-8 stainless steel, it provides corrosion resistance suitable for plumbing, HVAC, electrical, and general mechanical applications. The washer measures 9/32 inches inner diameter, 1 inch outer diameter, and 0.05 inches thick. The oversized outer diameter relative to the screw size distributes clamping load over a wider surface area, reducing the risk of pull-through in softer or thinner base materials. Maintenance technicians, plumbers, electricians, and pipefitters commonly use fender washers in both interior and exterior installations where moisture or chemical exposure is a concern.

This washer is suited for light commercial and residential trade applications where a larger bearing surface is required. Common install scenarios include pipe hangers, electrical panel mounting, HVAC equipment anchoring, and structural fastening in damp or corrosive environments. The 18-8 stainless steel grade performs reliably in wet service conditions, making it a practical choice for plumbing rough-in work, rooftop HVAC equipment, and poolside installations.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• Oversized 1-inch outer diameter distributes fastener load across a wider surface area
• 9/32-inch inner diameter fits standard 1/4-inch screws and bolts
• 0.05-inch thickness provides a low-profile bearing surface without adding significant stack height
• Inch measurement system — compatible with standard imperial fastener specifications

Compatibility

Designed as an OEM-style replacement or standard-service fender washer for use with 1/4-inch screw and bolt fasteners in imperial measurement applications.

Installation Notes

Installation requires no special tools beyond standard hand tools or a fastener driver. Always power down or de-energize electrical equipment and shut off fluid supply before working on systems where fasteners are being replaced or added. Verify that the selected washer material is compatible with the base material and environment to prevent galvanic corrosion when used alongside dissimilar metals. Follow applicable codes, including NEC or IPC guidelines, when using fasteners in electrical or plumbing assemblies.
