Professional Applications & Engineering Value
This hard fiber flat washer delivers critical engineering solutions where electrical insulation and chemical resistance are paramount. The Rockwell R70 hardness ensures consistent performance under compression, while the gray hard fiber material provides excellent dimensional stability across temperature fluctuations up to 230°F. Ideal for electrical panel assemblies, plumbing systems, and industrial equipment, these washers prevent galvanic corrosion between dissimilar metals and maintain sealing integrity in vibration-prone applications. The precise 0.375" ID and 2.25" OD dimensions ensure proper load distribution for 3/8" screw size fasteners, making them essential components in maintenance-critical environments where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to inch system standards with precise inner diameter of 0.375" and outer diameter of 2.25", this flat washer maintains consistent thickness between 0.120-0.130". The hard fiber material achieves Rockwell R70 hardness for optimal compression resistance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for international industrial applications.
