Professional Applications & Engineering Value

These UHMW plastic flat washers deliver critical performance advantages in demanding industrial applications where chemical exposure and consistent performance are paramount. The metric flat washer design with precise 2.1mm inner diameter ensures perfect compatibility with M2 screw assemblies, eliminating misalignment issues that compromise fastener integrity. The off-white UHMW material provides exceptional resistance to chemicals, moisture, and abrasion, making these plastic washers ideal for electronics, medical devices, food processing equipment, and laboratory instruments where metal corrosion or contamination cannot be tolerated. With a temperature range capability of 180°F, these washers maintain dimensional stability in environments where thermal cycling would degrade ordinary plastic components.

Specification Summary & Compliance

This M2 metric flat washer features precise dimensional specifications including 2.1mm inner diameter, 5mm outer diameter, and thickness ranging 0.7-0.9mm for consistent performance. Manufactured from UHMW plastic, these washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental and safety standards for industrial components. The washers are specifically engineered for use with M2 screw size applications requiring reliable, non-conductive, and chemically resistant spacing and load distribution solutions.
