It is used to distribute load across a fastened joint, protect surface finishes, and provide a stable seating surface for bolts and nuts. With an inside diameter of 0.395 inches, an outside diameter of 1 inch, and a thickness of 0.064 inches, this washer meets common dimensional standards for inch-system hardware. Plumbers, HVAC technicians, electricians, and general tradespeople reach for copper washers when corrosion resistance and conductivity matter. This listing covers a package quantity of 50 pieces.\u003c\/p\u003e\n\u003cp\u003eCopper flat washers are commonly used in plumbing, HVAC, and electrical installations where steel hardware would corrode or react with dissimilar metals or treated water. They are appropriate for use with copper pipe fittings, manifolds, valves, and electrical bonding connections. The plain finish means no added coating that could affect conductivity or seal performance. These washers are suited for both residential and light commercial applications where 3\/8 inch fasteners are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCopper material provides corrosion resistance and electrical conductivity\u003c\/li\u003e\n  \u003cli\u003ePlain finish with no additional coating for clean metal-to-metal contact\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.395 inches fits standard 3\/8 inch screws and bolts\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 1 inch distributes load across a wider bearing surface\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.064 inches meets standard flat washer profile\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 50 for jobsite and shop stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8 inch screws and bolts in inch-system fastener applications.
