- Superior chemical and wear resistance due to high-performance PEEK plastic construction, ensuring long service life in harsh industrial settings.
- Consistent dimensional accuracy with a 0.078" ID and 0.188" OD, providing a precise fit for No. 0 screws and reducing assembly errors.
- Enhanced load distribution and vibration resistance from the flat washer design, protecting sensitive components and extending equipment lifespan.
- High hardness (Rockwell M103) offers excellent mechanical strength, resisting indentation and maintaining seal integrity under pressure.
- Full compliance with ASME B18.21.1 standards, guaranteeing interchangeability and reliability in demanding engineering applications.
- Eco-friendly and safe for regulated industries with RoHS 3 and REACH compliance, meeting global environmental and health standards.
Professional Applications & Engineering Value
Engineered for demanding sectors, this PEEK plastic flat washer solves critical challenges in high-temperature and corrosive environments. Its beige color and PEEK material grade provide inherent resistance to chemicals, moisture, and thermal cycling, making it ideal for aerospace, automotive, and electronics assemblies. The precise 0.078" ID and 0.188" OD ensure secure fastening for No. 0 screw applications, reducing loosening from vibrations. By withstanding temperatures from -50°F to 500°F, it prevents common failures like cracking or melting, offering a durable, lightweight alternative to metal washers in weight-sensitive designs.
Specification Summary & Compliance
This washer adheres to ASME B18.21.1 specifications for dimensional consistency, with an inner diameter of 0.078", outer diameter of 0.188", and thickness ranging from 0.016" to 0.025". It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. Manufactured to inch system standards, it is designed for reliable performance in industrial fastening systems requiring high-temperature resilience and chemical inertness.
