Overview
This precision copper retaining washer is engineered to provide a durable, non-ferrous interface for shafts, bearings, and fasteners. Manufactured from pure copper, it delivers exceptional electrical conductivity and reliable corrosion resistance, making it an ideal component for both mechanical assembly and specialized electrical or thermal management applications. Its inherent malleability allows it to conform tightly to mating surfaces, creating an effective seal and compensating for minor surface imperfections. Supplied in a convenient package quantity of 100, this washer supports operational efficiency and inventory management in maintenance and production environments.
