Value Collection 38894 Copper Flat Washer 1/2 in 50 Pack

Product Description

The VALUE COLLECTION 38894 is a standard flat washer sized for 1/2 inch screws, manufactured from copper with a plain, uncoated finish. Flat washers in this configuration distribute load across a fastened joint, protect the mating surface, and reduce the risk of fastener pull-through. This washer measures 0.563 inches ID, 1.375 inches OD, and 0.091 inches thick. The copper construction provides natural corrosion resistance and is well suited for applications where galvanic compatibility with copper piping, fittings, or electrical components is required. Each package contains 50 washers sold as a single unit.

These flat washers are used in plumbing, electrical, and general mechanical assemblies where a 1/2 inch fastener is employed. Copper is a common choice in plumbing rough-in work, grounding applications, and corrosive environments where steel hardware would be inappropriate. They are suitable for both residential and light commercial installations and are handled by plumbers, electricians, and general contractors.

Key Features

• Copper material offers corrosion resistance and galvanic compatibility with copper systems
• Plain finish with no coating that could interfere with electrical conductivity or bonding
• 0.563 inches ID sized for 1/2 inch screws or bolts
• 1.375 inches OD provides broad load distribution across the fastened surface

Compatibility

Designed as a standard flat washer for use with 1/2 inch screws and bolts in inch-measurement fastener systems. Appropriate for applications requiring a copper-compatible or electrically conductive washer material.

Installation Notes

Installation is performed by the trade applicable to the assembly being fastened, including plumbers and electricians depending on the application. Ensure the fastener and mating hardware are compatible with copper to avoid adverse galvanic reactions. When used in electrical grounding or bonding applications, follow NEC requirements for hardware material and torque, referencing the fastener manufacturer for torque specifications. Do not use copper washers in assemblies where dissimilar metals could cause accelerated corrosion without appropriate isolation measures.
