Professional Applications & Engineering Value

This fiberglass flat washer delivers critical engineering solutions where conventional metal washers fail. The fiberglass construction provides exceptional electrical insulation properties, making it indispensable in electrical panels, control systems, and electronic enclosures where short-circuit prevention is paramount. Its high-temperature resistance to 280°F ensures reliable performance in thermal management applications, including motor assemblies, heating elements, and aerospace components. The material's inherent chemical resistance protects against degradation in chemical processing, marine, and industrial maintenance environments. With precise dimensions tailored for No. 1 screws, this washer eliminates compatibility issues while the Rockwell M100 hardness prevents compression set and maintains clamping force integrity under vibration and thermal cycling conditions.

Specification Summary & Compliance

This flat washer features precise inch system dimensions with 0.094" inner diameter and 0.25" outer diameter, manufactured to exacting standards for consistent performance. The product strictly complies with MIL-I-24768/27 military specifications for material and performance requirements. Environmental and safety compliance includes RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) compliance with the latest SVHC list update (06/14/2023, 235 substances). The fiberglass material maintains dimensional stability across the specified thickness range of 0.012-0.018" while providing the documented hardness characteristics and temperature resistance.
