Professional Applications & Engineering Value
This copper flat washer is engineered to address common challenges in electrical, marine, and industrial assembly, where corrosion resistance and electrical conductivity are critical. Made from pure copper, it prevents galvanic corrosion when paired with dissimilar metals and maintains stable electrical connections in panels, transformers, and grounding systems. The inch-system dimensions, including the precise 0.141" inner diameter, ensure a snug fit for No. 5 screws, reducing vibration-induced failures. Its thin, flat profile (0.024-0.038" thickness) distributes clamping force evenly, protecting soft surfaces and extending the life of assembled components in demanding settings like HVAC, automotive, and telecommunications infrastructure.
Specification Summary & Compliance
This flat washer adheres to standard inch-system tolerances, with an ID of 0.141", OD of 0.281", and thickness ranging from 0.024" to 0.038". It is manufactured for use with No. 5 screw sizes and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial and electronic applications.
