Professional Applications & Engineering Value
These Delrin® Acetal Plastic flat washers deliver exceptional engineering value in applications where metal components would compromise performance. The white Delrin material provides superior dielectric properties, making these plastic flat washers ideal for electrical insulation in electronic assemblies and control panels. Their inherent chemical resistance protects against solvents, fuels, and cleaning agents in industrial applications, while the low moisture absorption maintains dimensional stability in humid environments. The precise 0.12" ID x 0.25" OD dimensions with controlled 0.026-0.036" thickness ensure consistent performance as No. 4 screw washers, providing reliable spacing and load distribution without the risk of galvanic corrosion common with metal alternatives.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.12" inner diameter and 0.25" outer diameter specifications, these inch system washers maintain consistent 0.026-0.036" thickness for uniform performance. The components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet current environmental and safety standards for global industrial use. The Delrin® Acetal Plastic material provides reliable operation up to 180°F maximum temperature while maintaining mechanical properties and dimensional integrity.
