Value Collection 38891 Copper Flat Washer 1/4 in 100 Pack

Product Description

The VALUE COLLECTION 38891 is a standard flat washer sized for 1/4 inch screws, manufactured from copper with a plain finish. Each washer measures 0.250 inches inside diameter, 0.625 inches outside diameter, and 0.051 inches thick. Copper construction provides natural corrosion resistance and electrical conductivity, making these washers a practical choice in plumbing, electrical, and light mechanical assemblies where steel or zinc hardware is not appropriate. Licensed trades and maintenance professionals use flat washers like these to distribute load, prevent fastener pull-through, and protect mating surfaces. This listing covers a package of 100 individual washers.

These washers are suited for residential and light commercial applications where a 1/4 inch fastener is used and copper compatibility is required. Common install scenarios include plumbing fixture connections, grounding hardware assemblies, and general equipment maintenance. The plain finish keeps the copper surface uncoated, which is standard practice where soldering, brazing, or electrical contact with the washer is anticipated. Electricians, plumbers, and HVAC technicians frequently stock these in bulk for service work.

Installation Notes

Standard flat washers are installed by plumbers, electricians, and HVAC technicians as part of fastener assemblies. Always de-energize electrical circuits and shut off fluid supply lines before servicing connections where these washers are used. No special tooling is required for washer installation, but fastener torque should follow equipment manufacturer specifications for the host assembly. Copper washers used in electrical grounding applications must comply with applicable NEC requirements for the installation.
