Professional Applications & Engineering Value

This M18 metric flat washer addresses common industrial challenges like corrosion, friction, and thermal expansion. Crafted from lubricant-filled nylon plastic, it eliminates the need for external lubricants, reducing maintenance in automotive assemblies, electrical enclosures, and machinery. The material's inherent resistance to chemicals and moisture prevents galvanic corrosion when used with dissimilar metals, while the DIN 125 standard ensures precise threading compatibility. Its gray color allows for easy identification in complex assemblies, and the temperature range up to 220°F makes it suitable for engines or HVAC systems where thermal cycling occurs.

Specification Summary & Compliance

This washer features precise dimensions: 19mm inner diameter, 34mm outer diameter, and 2.7-3.3mm thickness, adhering to DIN 125 standards for metric flat washers. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The Rockwell M75 hardness confirms consistent material strength, and the manufacturing process meets industrial specifications for reliable performance in M18 screw applications.
