Key Features & Benefits at a Glance
- Extreme temperature resilience for reliable performance from -30°F to 450°F, ensuring stability in harsh thermal environments
- Superior chemical resistance with Ultem PEI plastic construction, preventing degradation from corrosive substances
- High hardness rating (Rockwell M114) delivers excellent wear resistance and maintains shape under load
- Precision dimensional compliance with DIN 125 standards for consistent fit and reliable load distribution
- Broad regulatory compliance including RoHS 3 and REACH, meeting stringent industrial safety requirements
- Optimal size compatibility with M3 screws (3.2mm ID, 7mm OD) for easy integration into metric assemblies
- Minimal thickness variance (0.4-0.6mm) enables uniform pressure distribution in tight spaces
Professional Applications & Engineering Value
These M3 metric flat washers manufactured from Ultem PEI plastic solve critical engineering challenges in extreme environments. The high-temperature resistance up to 450°F makes them ideal for automotive, aerospace, and electronics applications where thermal cycling causes metal washers to fail. The chemical-resistant properties prevent swelling and degradation when exposed to fuels, solvents, and cleaning agents. With DIN 125 compliance, these washers provide precise dimensional stability for consistent bolt load distribution, eliminating loosening in vibrating machinery. The Rockwell M114 hardness ensures long-term performance in high-wear industrial applications while maintaining electrical insulation properties.
Specification Summary & Compliance
Manufactured to DIN 125 specifications with precise dimensions: 3.2mm ID, 7mm OD, and 0.4-0.6mm thickness for M3 screw compatibility. These Ultem PEI plastic washers meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety and regulatory adherence for global industrial applications. The manufacturing process maintains tight tolerances for consistent performance across temperature extremes from -30°F to 450°F.
