Professional Applications & Engineering Value

Engineered for precision metric fastener systems, these M3 flat washers solve critical assembly challenges in industrial equipment and machinery. The zinc-plated steel construction provides essential galvanic protection against moisture and chemical exposure, while the precisely calibrated 3.5mm inner diameter prevents thread interference with M3 screws. Manufacturers benefit from the controlled thickness variation (0.8-1.2mm) that compensates for surface irregularities, ensuring uniform clamping force distribution. These ASME B18.22M compliant washers deliver reliable performance in automotive subassemblies, electrical enclosures, and precision instrumentation, where dimensional consistency and REACH compliance are mandatory for international supply chain integration.

Specification Summary & Compliance

Manufactured to ASME B18.22M dimensional standards with metric measurements (3.5mm ID × 9.9mm OD × 0.8-1.2mm thickness). The zinc-plated steel construction meets industrial corrosion protection requirements while maintaining full compliance with REACH (EC 1907/2006) regulations regarding SVHC substances. These flat washers are specifically engineered for M3 screw applications with standardized dimensions ensuring seamless integration into global metric assembly systems.
