Professional Applications & Engineering Value
These carbon-filled PEEK flat washers deliver critical engineering solutions where traditional metal washers fail. The 30% carbon reinforcement in the PEEK polymer matrix creates a washer that maintains dimensional stability under extreme thermal cycling from -20°F to 500°F, preventing deformation in high-temperature applications like aerospace components, automotive systems, and chemical processing equipment. The DIN 125 specification ensures precise dimensional tolerances for reliable mating with M3 metric fasteners, while the material's inherent chemical resistance protects against degradation in harsh environments. This combination addresses common industrial challenges including galvanic corrosion prevention, weight reduction requirements, and maintenance reduction in hard-to-service applications.
Specification Summary & Compliance
Manufactured to DIN 125 standard with precise dimensional tolerances (ID: 3.2 mm, OD: 7 mm, Thickness: 0.4-0.6 mm) for M3 screw applications. These washers feature carbon-filled PEEK plastic with 30% filler material and Rockwell M103 hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
