S-93785A300 0.15" ID x 0.38" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional thermal stability for reliable performance in extreme environments from -50°F to 500°F, preventing deformation and maintaining load distribution.
• Superior chemical resistance thanks to PEEK plastic material, ideal for harsh industrial settings where corrosion or chemical exposure is a concern.
• High hardness (Rockwell M103) ensures excellent wear resistance and durability, extending the washer's service life under mechanical stress.
• Precision dimensional fit with 0.15" ID and 0.38" OD designed specifically for No. 6 screws, providing secure fastening and vibration reduction.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and suitability for global industrial supply chains.
• Versatile thickness range (0.020-0.060") allows for fine-tuning in assembly to accommodate varying gap and tension requirements.
• Lightweight and non-conductive properties of PEEK plastic reduce overall weight and eliminate electrical risks in sensitive applications.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these PEEK plastic flat washers address critical challenges in high-temperature and chemically aggressive settings. The PEEK material offers inherent resistance to a wide range of chemicals, solvents, and steam, making these inch washers ideal for applications in aerospace, automotive, and chemical processing industries. Their ability to maintain mechanical integrity from -50°F to 500°F ensures consistent performance in thermal cycling, preventing common failures like cracking or loss of clamp load. The precise 0.15" ID and 0.38" OD dimensions for No. 6 screws provide optimal bearing surface, reducing stress concentration and enhancing joint reliability. This combination of high-temperature resistance, dimensional accuracy, and regulatory compliance delivers long-term value by minimizing maintenance downtime and replacement costs in critical assemblies.
