Professional Applications & Engineering Value

This Delrin® Acetal Plastic flat washer is engineered to solve critical challenges in industrial and engineering applications. Its chemical-resistant properties make it ideal for use in environments exposed to solvents, fuels, and other aggressive substances, preventing the failure common with metallic washers. The material's inherent low moisture absorption ensures dimensional stability, while its high strength-to-weight ratio and Durometer 83D hardness provide excellent load distribution and vibration resistance. These white flat washers are perfect for electrical assemblies to prevent galvanic corrosion, food processing equipment due to their non-toxic nature, and precision mechanical systems where low friction and minimal particulate generation are paramount. The specific design for a No. 4 screw size guarantees a secure fit, enhancing the reliability of the entire fastening system.
