• High-temperature resistance up to 230°F, maintaining structural integrity in demanding thermal environments
• Corrosion-resistant non-metallic construction, ideal for use in humid or chemically aggressive settings without rust concerns
• Precision dimensional fit with 0.375" ID and 0.5" OD ensuring proper alignment and seating on 3/8" fasteners
• Full regulatory compliance with RoHS 3 and REACH standards, meeting international environmental and safety requirements
• Consistent 0.028-0.034" thickness providing reliable sealing and spacing performance across industrial applications

Professional Applications & Engineering Value

These red hard fiber flat washers deliver critical engineering solutions where electrical isolation and thermal stability are paramount. The hard fiber material provides exceptional dielectric strength, making them ideal for electrical assemblies, control panels, and electronic enclosures where current insulation is required. Their non-metallic composition eliminates galvanic corrosion risks when used with dissimilar metals, while the precise 0.375" ID ensures secure fitment on 3/8" screws without slippage. The 0.5" OD offers optimal surface coverage for distributing clamp loads effectively across softer materials or finished surfaces. These flat washers maintain performance in applications up to 230°F, serving reliably in motor mounts, transformer installations, and industrial equipment where temperature fluctuations occur.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.375" inner diameter and 0.5" outer diameter, these washers feature a controlled thickness range of 0.028-0.034" for consistent performance. Designed specifically for 3/8" screw size applications in inch measurement systems. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance adherence. The hard fiber construction provides reliable mechanical properties without hardness rating requirements, suitable for various industrial fastening scenarios.
