Au-ve-co Products 19604 M14 Copper Flat Washer

Product Description

The AU-VE-CO PRODUCTS 19604 is a standard flat washer sized for M14 metric fasteners and made from copper. It seats between a fastener head or nut and the mating surface to distribute clamp load and protect the base material. The washer measures 16mm inside diameter, 22mm outside diameter, and 1.5mm thick, following standard metric proportions for M14 hardware. Copper construction provides corrosion resistance and electrical conductivity, making it a common choice in plumbing, electrical, and refrigeration assemblies where galvanic compatibility or sealing properties matter. Plumbers, HVAC technicians, and electricians are the primary installers of this type of hardware.

This washer is suited for metric fastener applications in residential and light commercial systems. Typical install scenarios include pipe flange connections, equipment mounting, and electrical grounding assemblies where a copper interface is required. It is sold individually but subject to a minimum order quantity of 10 pieces, making it appropriate for both service-call restocking and small project builds.

Key Features

• Copper material offers natural corrosion resistance and electrical conductivity
• M14 screw size with 16mm inside diameter for standard metric fitment
• 22mm outside diameter distributes clamp load across a broad bearing surface
• 1.5mm thickness conforms to standard metric flat washer proportions
• Metric measurement system throughout for compatibility with metric fastener sets

Compatibility

Designed as a standard metric flat washer for use with M14 screws and bolts in plumbing, HVAC, electrical, and general mechanical assemblies requiring copper hardware.

Installation Notes

Install by a licensed plumber, electrician, or HVAC technician as appropriate to the application. De-energize electrical circuits or shut off fluid supply before servicing any connection point. Use standard hand tools; avoid overtightening, which can deform the soft copper washer and compromise the seal or clamp load. Verify that copper is compatible with mating metals in the assembly to avoid galvanic corrosion issues.
