- Consistent load distribution with 0.7-0.9mm thickness range protects sensitive surfaces from damage
- Reliable performance in elevated temperatures up to 150°F maintains structural integrity
- Superior surface protection with Rockwell R85 hardness prevents embedding and surface marring
- Full regulatory compliance with RoHS 3 and REACH standards for global market acceptance
- Non-conductive and corrosion-resistant properties make ideal for electrical and electronic assemblies
Professional Applications & Engineering Value
These M2 metric flat washers provide essential engineering solutions where metal alternatives would cause galvanic corrosion or electrical shorting. The polypropylene plastic construction offers exceptional dielectric properties, making them perfect for electronic assemblies, PCB mounting, and sensitive instrumentation. The off-white color allows for easy visual inspection and quality control during assembly processes. With precise 2.2mm inner diameter and 5mm outer diameter, these washers deliver consistent load distribution while preventing screw head embedding in soft materials. The 0.7-0.9mm thickness range accommodates manufacturing tolerances while maintaining reliable spacing and tension control in industrial applications requiring non-metallic fastening solutions.
Specification Summary & Compliance
Manufactured to precise metric dimensions with 2.2mm ID and 5mm OD specifically designed for M2 screw applications. The 0.7-0.9mm thickness provides consistent performance across production batches. These flat washers feature Polypropylene Plastic material with Rockwell R85 hardness and temperature resistance up to 150°F. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial and electronic applications.
