Professional Applications & Engineering Value
This nylon self-retaining washer is engineered to address common industrial challenges such as vibration-induced loosening and component wear. Made from high-hardness nylon plastic with Rockwell R120 rating, it maintains structural integrity under mechanical stress and extreme temperatures from -40°F to 180°F. The self-retaining feature secures the washer in place during assembly, streamlining installation in automotive, electronics, and machinery applications where 1/4" and M6 screws are used. Its non-metallic composition prevents galvanic corrosion and electrical conductivity, making it ideal for sensitive equipment. By combining precise 0.45" ID and 1.5" OD dimensions with robust material properties, this washer enhances operational safety and reduces downtime in demanding environments.
Specification Summary & Compliance
This washer meets standard dimensional tolerances for inch and metric systems, with an internal diameter of 0.45", outer diameter of 1.5", and thickness ranging from 0.052" to 0.072". It is manufactured from nylon plastic with a hardness of Rockwell R120 and complies with RoHS 3 (2015/863/EU) regulations, ensuring adherence to environmental and safety standards for industrial components.
