Professional Applications & Engineering Value

These phenolic plastic flat washers deliver critical performance advantages in electrical insulation applications where metal washers would cause short circuits. The Brown phenolic material provides inherent chemical resistance against industrial fluids and solvents, making them ideal for automotive, aerospace, and electronic enclosures. With a maximum temperature rating of 250°F, these metric washers maintain structural integrity in thermally challenging environments while the Rockwell M95 hardness ensures they won't deform under bolt torque. The precise 2.2mm ID and 5mm OD dimensions guarantee perfect alignment with M2 screw sizes, eliminating installation issues in precision assemblies.

Specification Summary & Compliance

Manufactured to metric system standards with precise internal diameter (2.2mm), outer diameter (5mm), and controlled thickness (0.7-0.9mm). These flat washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they're free from restricted substances. The phenolic plastic construction meets industrial requirements for electrical insulation applications while providing consistent performance across the specified temperature range up to 250°F.
