S-93785A540 21 mm ID x 37 mm OD DIN 125 Plastic Washers

Key Features & Benefits at a Glance

• Exceptional thermal stability for reliable performance in extreme environments from -20°F to 500°F
• Superior chemical resistance thanks to PEEK plastic construction, ideal for harsh industrial applications
• Consistent load distribution with precise 21mm ID and 37mm OD dimensions per DIN 125 standards
• Long-lasting durability maintained through Rockwell M103 hardness under mechanical stress
• Regulatory compliance assurance with RoHS 3 and REACH adherence for global supply chain integration
• Optimized thickness tolerance (2.7-3.3mm) ensuring secure fit and vibration resistance in M20 screw assemblies
• Lightweight yet robust PEEK material reducing overall weight without compromising structural integrity

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this PEEK plastic flat washer delivers critical performance where metal components fail. Its high-temperature resistance (500°F maximum) prevents deformation in thermal cycling applications like automotive engine compartments and aerospace systems. The metric M20 sizing with DIN 125 compliance ensures precise fitment in European machinery and equipment. Chemical inertness makes it ideal for chemical processing plants and medical devices where corrosion resistance is paramount. The Rockwell M103 hardness provides lasting surface protection against wear in high-vibration environments, while the 3mm thickness maintains consistent clamping force in bolted connections.
