Professional Applications & Engineering Value

Engineered for demanding industrial environments, these fiberglass flat washers deliver critical performance advantages in high-temperature and electrical applications. The fiberglass material composition provides excellent thermal stability, preventing washer failure in equipment operating near 280°F maximum temperature. This makes them ideal for electrical insulation in motor assemblies, transformer installations, and heating element applications where metallic washers would conduct electricity or degrade. The precise No. 4 screw size compatibility ensures proper load distribution while the consistent 0.012-0.018" thickness maintains uniform clamping force. These industrial washers solve common engineering challenges by combining thermal resistance with electrical isolation in a single, compliant component.
