S-95331A702 8.4 mm ID x 16 mm OD DIN 125 Plastic Washers

Key Features & Benefits at a Glance

• Exceptional thermal stability with a wide operating range from -30°F to 450°F, ensuring reliable performance in extreme temperature environments.
• Superior mechanical strength provided by Ultem PEI plastic and Rockwell M114 hardness, offering excellent resistance to deformation under load.
• Precise dimensional compatibility with M8 screws (8.4mm ID, 16mm OD) and controlled thickness (1.4-1.8mm), guaranteeing secure fit and uniform load distribution.
• DIN 125 certification ensures standardized quality and interchangeability in metric assemblies, reducing installation errors.
• Chemical and environmental resistance due to high-performance plastic construction, ideal for corrosive or demanding industrial settings.
• Regulatory compliance with RoHS 3 and REACH standards, supporting safe and sustainable manufacturing practices.
• Lightweight and non-conductive properties minimize component weight and prevent electrical interference in sensitive applications.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M8 metric flat washers made from Ultem PEI plastic address critical challenges in high-temperature and corrosive settings. The black plastic construction provides inherent resistance to chemicals, moisture, and wear, while the DIN 125 specification ensures precise dimensional accuracy for consistent performance in automotive, aerospace, and electronics assemblies. With a temperature range of -30°F to 450°F, these washers prevent thermal degradation and maintain clamping force in applications such as thermal management systems, electrical enclosures, and machinery subjected to cyclic heating. The combination of Rockwell M114 hardness and compliant standards reduces maintenance needs and enhances operational longevity.
