Professional Applications & Engineering Value
These hard fiber flat washers deliver critical engineering solutions where electrical insulation and thermal resistance are paramount. The hard fiber material composition prevents galvanic corrosion while providing excellent dielectric properties, making them ideal for electrical assemblies and electronic enclosures. The Rockwell R80 hardness ensures dimensional stability under compression, maintaining seal integrity in automotive components and industrial machinery. With their 0.375" OD and precise No. 4 screw size compatibility, these black fiber washers effectively distribute clamping force while resisting degradation in environments up to 230°F, solving common challenges in thermal management and vibration resistance applications.
Specification Summary & Compliance
Manufactured to inch system standards with precise dimensional tolerances: 0.126" inner diameter, 0.375" outer diameter, and thickness range of 0.036-0.044". These flat washers comply with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, ensuring environmental safety and regulatory adherence for industrial applications.
