Professional Applications & Engineering Value

This fiberglass flat washer delivers critical performance advantages in demanding thermal and electrical applications where conventional metal washers fail. The fiberglass material provides excellent electrical insulation while resisting corrosion in industrial environments exposed to chemicals and moisture. Engineered to withstand temperatures up to 280°F, these washers maintain dimensional stability in high-heat applications such as electrical enclosures, HVAC systems, and industrial machinery. The 0.625" ID and 2" OD dimensions ensure precise fitment for 5/8" fasteners, distributing load effectively while preventing galvanic corrosion between dissimilar metals. The Rockwell M100 hardness ensures the washer retains its form under pressure, making it ideal for vibration-prone assemblies where maintaining clamp load is critical.
