Professional Applications & Engineering Value

This fiberglass flat washer delivers critical performance advantages in demanding industrial applications where temperature extremes and electrical safety are primary concerns. The fiberglass material provides outstanding thermal stability up to 280°F, preventing the softening or melting issues common with plastic washers. Its inherent electrical insulation properties make it ideal for electrical enclosures, motor assemblies, and power distribution systems where current isolation is essential. The Rockwell M100 hardness ensures the washer maintains its form under heavy clamping loads, preventing compression set and maintaining bolt tension. These high-temperature washers solve critical engineering challenges in HVAC systems, automotive components, and industrial machinery where both thermal performance and electrical safety are non-negotiable requirements.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with 0.25" ID and 2" OD, this flat washer features thickness ranging from 0.108" to 0.142" for compatibility with 1/4" screw sizes. The product fully complies with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) standards regarding substance restrictions, ensuring environmental responsibility and workplace safety. The fiberglass construction meets industrial requirements for thermal performance and electrical insulation, making it suitable for various heavy-duty applications where material integrity and regulatory compliance are essential.
