Professional Applications & Engineering Value

This fiberglass flat washer delivers critical engineering solutions where standard metal washers fail. The fiberglass material provides inherent electrical insulation while maintaining structural integrity under thermal stress up to 280°F, making it ideal for electrical enclosures, aerospace components, and chemical processing equipment. The light green color coding enables quick visual identification during assembly, while the precise 0.105" inner diameter ensures secure seating on No. 3 screws. Unlike metallic alternatives, this washer eliminates galvanic corrosion risks and provides consistent performance in environments with temperature fluctuations, chemical exposure, or electrical current concerns. The combination of MIL-I-24768/27 compliance and industrial-grade fiberglass construction addresses the critical need for reliable, non-conductive spacing and load distribution in demanding applications.

Specification Summary & Compliance

This flat washer features precise inch system dimensions with 0.105" inner diameter, 0.250" outer diameter, and controlled thickness range of 0.024-0.038". Manufactured to meet MIL-I-24768/27 military specifications for material and performance requirements. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical substances. With Rockwell M100 hardness rating and fiberglass composition, this component maintains dimensional stability and mechanical properties across its specified temperature range up to 280°F.
