S-91545A480 10.5 mm ID x 20 mm OD DIN 125 Plastic Washers

Key Features & Benefits at a Glance

• Self-lubricating design reduces friction during installation and prevents seizing, extending component life
• Excellent corrosion resistance from nylon plastic material, ideal for humid or chemically exposed environments
• Consistent performance up to 220°F maintains dimensional stability and mechanical properties in elevated temperatures
• Rockwell M75 hardness provides durable bearing surface and reliable load distribution under M10 fasteners
• Precision DIN 125 dimensions ensure perfect fit with metric M10 screws (10.5mm ID, 20mm OD) for secure assemblies
• Regulatory compliance with RoHS 3 and REACH standards meets global environmental and safety requirements
• Reduced maintenance needs through integrated lubricant eliminates requirement for external lubricants

Professional Applications & Engineering Value

This lubricant-filled nylon plastic flat washer solves critical assembly challenges in industrial applications where metal fasteners are problematic. The M10 metric flat washer combines the chemical resistance of engineering plastic with built-in lubrication, eliminating galling and corrosion issues common with steel washers. Its Rockwell M75 hardness provides sufficient compressive strength for electrical enclosures, automotive components, and food processing equipment while maintaining electrical insulation properties. The DIN 125 standard ensures dimensional precision for reliable performance in automated assembly systems, reducing installation time and preventing thread damage. With a 220°F temperature rating, this gray washer maintains integrity in environments where thermal cycling would degrade ordinary plastic washers.

Specification Summary & Compliance

Manufactured to DIN 125 specifications with precise dimensions: 10.5mm internal diameter, 20mm outer diameter, and 1.8-2.2mm thickness range for M10 screw applications. The lubricant-filled nylon plastic construction meets Rockwell M75 hardness standards for consistent performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, with temperature capability to 220°F maximum operating conditions.
