It provides a bearing surface that distributes load, reduces friction, and protects mating surfaces during assembly. The washer measures 20mm inside diameter, 24mm outside diameter, and 1.5mm in thickness. Copper construction offers corrosion resistance and electrical conductivity, making this washer suitable for plumbing, electrical, and HVAC applications where ferrous hardware would corrode or introduce unwanted galvanic interaction. Trades professionals sourcing metric hardware for copper piping connections, bonding applications, or corrosive environments will find this a direct fit for M18 fastener assemblies.\u003c\/p\u003e\u003cp\u003eThis washer is intended for metric fastener applications across residential and light commercial systems. It is commonly used in plumbing, refrigeration, and mechanical assemblies where M18 hardware is specified and copper material compatibility is required. The metric sizing makes it appropriate for equipment and systems built to international or metric standards. It ships with a minimum order quantity of 25 pieces, suitable for stocking or job-lot purchasing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCopper material provides corrosion resistance and electrical conductivity\u003c\/li\u003e\n\u003cli\u003eStandard flat washer profile for load distribution on M18 metric fasteners\u003c\/li\u003e\n\u003cli\u003e20mm inside diameter fits M18 screw shank with appropriate clearance\u003c\/li\u003e\n\u003cli\u003e24mm outside diameter provides a stable bearing surface\u003c\/li\u003e\n\u003cli\u003e1.5mm thickness meets standard metric washer specifications\u003c\/li\u003e\n\u003cli\u003eMetric system sizing for compatibility with internationally dimensioned fastener assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric flat washer for use with M18 fasteners in plumbing, HVAC, electrical, and mechanical assemblies requiring copper hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by the applicable licensed trade based on the system being serviced, including plumbers, HVAC technicians, or electricians.
