Value Collection CFLW063OP-025BX Flat Washer 5/8 in Copper

Product Description

The VALUE COLLECTION CFLW063OP-025BX is a standard flat washer sized for 5/8 inch screws, manufactured from copper with a plain finish. Flat washers distribute load across a fastened joint, protecting the mating surface and reducing the risk of loosening under vibration. This washer measures 0.688 inches inner diameter, 1.75 inches outer diameter, and 0.102 inches thick. The copper construction makes it well suited for applications where corrosion resistance, electrical conductivity, or compatibility with copper piping and fittings is required. Plumbers, electricians, and mechanical contractors install these washers in both new construction and service work where steel hardware would cause galvanic corrosion or contamination concerns.

Standard flat washers in this size class are used in residential and light commercial plumbing, electrical panel work, HVAC equipment mounting, and general mechanical assembly. The 5/8 inch screw size fits common fastener patterns found in pipe flanges, equipment brackets, and structural connections. The plain finish means no added coating or plating, keeping the copper surface natural and compatible with soldering or bonding where required by the application.

Key Features

• Copper material resists corrosion and suits applications requiring galvanic compatibility with copper components
• Plain finish preserves the natural copper surface for soldering or bonding compatibility
• 0.688 inch inner diameter sized for 5/8 inch screws or bolts
• 1.75 inch outer diameter provides broad load distribution across fastened surfaces
• 0.102 inch thickness meets standard flat washer geometry for this screw size
• Inch measurement system for compatibility with standard imperial fastener specifications

Compatibility

Designed as a standard flat washer for use with 5/8 inch screws and bolts in inch-system fastener applications requiring copper material.

Installation Notes

Plumbers, electricians, and mechanical contractors install flat washers as part of bolted or screwed joint assemblies. Power down or depressurize the system before servicing any fastened connection. Verify that copper hardware is appropriate for the mating materials in the joint to avoid unintended galvanic reactions with dissimilar metals. Follow applicable codes such as the NEC or IPC for fastener material requirements in electrical or plumbing installations.
