• Precise dimensional fit with 0.312" inner diameter and 0.562" outer diameter, ensuring secure seating on 5/16" screws
• Uniform load distribution from consistent 0.028-0.034" thickness, reducing stress on fastened components
• Full regulatory compliance with RoHS 3 and REACH standards, supporting global supply chain requirements
• Vibration dampening capability to minimize loosening and noise in mechanical systems

Professional Applications & Engineering Value

This red hard fiber flat washer delivers critical performance in applications where metal washers fall short. Its non-conductive properties make it indispensable in electrical enclosures, control panels, and wiring terminals, preventing short circuits and galvanic corrosion. The hard fiber material resists oils, solvents, and moisture, ensuring longevity in industrial machinery, automotive systems, and outdoor equipment. With a temperature range up to 230°F, it reliably functions in heated assemblies without degrading. The precise inch dimensions (0.312" ID, 0.562" OD) and flat washer design provide consistent sealing and spacing, solving common issues like fastener embedment and surface damage in soft materials.

Specification Summary & Compliance

This flat washer conforms to standard inch system measurements with an inner diameter of 0.312", outer diameter of 0.562", and thickness tolerance of 0.028-0.034". It is designed for use with 5/16" screw sizes. The product is manufactured from hard fiber material and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances. No hardness rating is specified, as it is a non-metallic component.
