• Consistent dimensional accuracy with precise 3.2mm ID and 7mm OD for secure M3 screw fit and alignment
• Enhanced durability with Rockwell M75 hardness providing reliable load distribution and resistance to deformation
• Broad thermal stability maintaining performance in applications up to 220°F (104°C)
• Regulatory compliance with RoHS 3 and REACH standards for safe use in regulated industries
• Standardized reliability through DIN 125 specification ensuring interchangeability and quality consistency

Professional Applications & Engineering Value

These M3 metric flat washers deliver exceptional engineering value through their unique lubricant-filled nylon plastic construction. The integrated lubricant significantly reduces installation torque and prevents galling in repeated assembly applications, solving common friction-related issues in manufacturing and maintenance operations. The gray color provides visual distinction in complex assemblies, while the material's inherent corrosion resistance eliminates concerns about rust in humid or chemical-exposed environments. These DIN 125 compliant washers are particularly valuable in electrical enclosures, automotive components, and food processing equipment where non-conductive, non-marring fastening solutions are essential. The combination of temperature resistance to 220°F and regulatory compliance makes them ideal for industrial applications requiring both performance and safety certifications.

Specification Summary & Compliance

This precision flat washer features exact dimensional specifications with 3.2mm inner diameter, 7mm outer diameter, and 0.4-0.6mm thickness range, ensuring proper fit for M3 screw applications. Manufactured to DIN 125 standards for dimensional consistency and performance reliability. The product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and meets REACH (EC 1907/2006) requirements for chemical safety. The lubricant-filled nylon material with Rockwell M75 hardness provides consistent mechanical properties across the specified temperature range up to 220°F maximum.
