Professional Applications & Engineering Value

Engineered for challenging environments where metal washers fail, this carbon-filled PEEK plastic flat washer delivers exceptional performance in high-temperature applications up to 500°F while maintaining integrity at cryogenic conditions down to -50°F. The 30% carbon filler reinforcement provides superior dimensional stability and wear resistance, preventing deformation under load in industrial assembly scenarios. Perfect for No. 8 screw applications requiring electrical insulation, chemical resistance, or weight reduction, these ASME B18.21.1 compliant washers eliminate galvanic corrosion concerns while offering reliable load distribution. The black plastic construction ensures consistent performance in automotive, aerospace, and chemical processing equipment where thermal cycling and aggressive media would compromise conventional materials.

Specification Summary & Compliance

This flat washer features precise inch system dimensions with 0.19" inner diameter and 0.44" outer diameter, manufactured to ASME B18.21.1 standards for dimensional consistency and performance reliability. The carbon-filled PEEK material with 30% filler content ensures mechanical stability across the specified thickness range of 0.036-0.065". Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and global market acceptance, while the Rockwell M103 hardness rating confirms superior wear resistance for extended service life in demanding applications.
