S-93785A520 17 mm ID x 30 mm OD DIN 125 Plastic Washers

Key Features & Benefits at a Glance

• Exceptional thermal stability maintains performance across a wide temperature range from -20°F to 500°F, preventing deformation in extreme environments
• Superior chemical resistance ensures long-term reliability when exposed to aggressive industrial chemicals and solvents
• High hardness rating (Rockwell M103) provides excellent dimensional stability and load distribution for M16 screw applications
• Precision manufacturing to DIN 125 standards guarantees consistent dimensions (17mm ID, 30mm OD, 2.6-3.1mm thickness) and reliable fit
• Regulatory compliance with RoHS 3 and REACH standards makes these washers suitable for sensitive industrial and electronic applications
• Reduced maintenance requirements due to PEEK material's inherent durability and resistance to wear and degradation
• Electrical insulation properties prevent current leakage in electrical assemblies and high-voltage applications

Professional Applications & Engineering Value

This PEEK plastic flat washer delivers critical engineering solutions for demanding industrial environments where metal components fail. The high-temperature resistance up to 500°F makes it ideal for automotive, aerospace, and chemical processing equipment where thermal cycling is common. Its chemical inertness prevents corrosion and degradation when exposed to harsh solvents, acids, and bases, extending service life in chemical processing plants and laboratory equipment. The DIN 125 specification ensures precise dimensional control for reliable performance in M16 screw assemblies, while the Rockwell M103 hardness provides sufficient compressive strength for load-bearing applications. These washers solve common challenges in electrical insulation, thermal management, and chemical exposure, making them essential components in manufacturing, energy, and transportation sectors where reliability under extreme conditions is paramount.
