Professional Applications & Engineering Value
This M6 Delrin® flat washer delivers exceptional engineering value in applications where metal fasteners fail. The acetal plastic construction provides inherent corrosion resistance, eliminating galvanic corrosion risks in mixed-material assemblies while offering reliable electrical insulation for sensitive electronic equipment. Its low moisture absorption and chemical resistance make it ideal for food processing, medical devices, and automotive components exposed to fuels and lubricants. The metric dimensions (6.4mm ID × 12mm OD) ensure precise alignment with M6 screws, while the white color allows for easy identification in automated assembly processes. With thermal stability up to 180°F, this washer maintains performance in elevated temperature environments where plastic deformation would typically occur.
Specification Summary & Compliance
This metric flat washer features precise dimensional tolerances with 6.4mm internal diameter, 12mm outer diameter, and 1.4-1.8mm thickness range, engineered for optimal performance with M6 screw sizes. Manufactured from Delrin® Acetal Plastic with Rockwell M90 hardness rating, it delivers consistent mechanical properties across applications. The product fully complies with RoHS 3 (2015/863/EU) restrictions and REACH (EC 1907/2006) regulations regarding substance control, ensuring environmental safety and regulatory acceptance in global markets.
