Au-ve-co Products 23912 M5 Copper Flat Washer

Product Description

The AU-VE-CO PRODUCTS 23912 is a standard flat washer designed for use with M5 metric screws. Manufactured from copper, this washer measures 6mm inside diameter, 12mm outside diameter, and 1mm thick. It distributes load evenly across the fastener bearing surface, reducing the risk of surface damage and loosening under vibration. Copper construction provides natural corrosion resistance and mild electrical conductivity, making it suitable for installations where galvanic compatibility or conductivity is a consideration. Plumbers, HVAC technicians, and electricians commonly use copper washers in mechanical assemblies and pipe connections where standard steel hardware is not appropriate.

This washer is suited for light-duty metric fastener applications in residential and commercial installations. Typical use cases include equipment mounting, pipe flange connections, and terminal block assemblies where an M5 fastener is used. The metric sizing follows standard ISO dimensions, making it straightforward to source matching hardware. Minimum order quantity is 100 pieces, and each unit is sold individually within that minimum purchase requirement.

Compatibility

Designed as a standard metric flat washer for use with M5 screws in plumbing, HVAC, electrical, and general mechanical assemblies where copper hardware is specified.

Installation Notes

Installation requires no special tools beyond standard hand tools appropriate for the fastener being used. Ensure mating surfaces are clean and free of debris before seating the washer. When using copper washers in electrical assemblies, follow applicable NEC guidelines for hardware selection and torque procedures. Do not mix copper hardware with ferrous fasteners in environments where galvanic corrosion is a concern.
