Professional Applications & Engineering Value

Engineered for demanding industrial settings, this fiberglass flat washer solves critical challenges in high-temperature and electrical applications. Its fiberglass composition provides inherent non-conductive insulation, preventing electrical shorts in machinery and control panels. The washer maintains structural integrity under thermal stress up to 280°F, eliminating deformation issues common with plastic or metal alternatives in heating systems, automotive components, and processing equipment. With precise 1/4" screw compatibility and consistent 0.5" OD dimensions, it ensures reliable load distribution while resisting chemical exposure and moisture – making it indispensable for electrical insulation and thermal management in OEM manufacturing and MRO operations.

Specification Summary & Compliance

This flat washer conforms to inch system standards with inner diameter of 0.25", outer diameter of 0.5", and thickness ranging 0.024-0.038". Manufactured from fiberglass with Rockwell M100 hardness, it demonstrates consistent dimensional accuracy for 1/4" screw applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to restricted substance directives and environmental safety protocols for industrial use.
