PEEK Metric Flat Washers conforming to ISO 7089 are engineered for demanding applications requiring exceptional mechanical strength, thermal stability, and chemical resistance. Manufactured from high-performance Polyether Ether Ketone (PEEK), these washers provide reliable load distribution and surface protection while maintaining their mechanical properties in extreme operating environments.
Designed for use with metric fasteners, PEEK flat washers help distribute clamping forces evenly, reduce surface damage, and improve joint integrity. Their outstanding dimensional stability, low moisture absorption, and resistance to aggressive chemicals make them ideal for aerospace, semiconductor, medical, and chemical processing applications where conventional plastic washers may be unsuitable.
