- Precise dimensional accuracy with 3.5mm ID and 11.8mm OD ensures perfect fit for M3 screws and consistent performance
- Optimized load distribution through controlled 1.0-1.4mm thickness range prevents surface damage and loosening
- Industry-standard compliance with ASME B18.22M guarantees interchangeability and reliable mechanical properties
- Environmental responsibility with REACH compliance for safe use across regulated industrial applications
- Enhanced fastener protection by absorbing vibration and preventing galvanic corrosion between dissimilar metals
- Cost-effective maintenance through durable steel construction that withstands repeated assembly and disassembly
Professional Applications & Engineering Value
These M3 metric flat washers deliver exceptional engineering value in industrial fastening systems where vibration resistance and corrosion protection are critical. The zinc-plated steel construction provides a sacrificial layer that significantly extends component life in humid or chemically aggressive environments. With precise 3.5mm internal diameter and 11.8mm outer diameter, these washers ensure perfect alignment with M3 fasteners while distributing clamp load effectively across joined surfaces. This prevents material deformation, reduces stress concentration, and maintains joint integrity in machinery, electrical enclosures, and automotive assemblies. The controlled thickness variation (1.0-1.4mm) accommodates manufacturing tolerances while maintaining consistent performance across high-volume production applications.
Specification Summary & Compliance
Manufactured to ASME B18.22M dimensional standards with precise metric specifications: 3.5mm ID, 11.8mm OD, and 1.0-1.4mm thickness range. Constructed from zinc-plated steel for corrosion protection. Fully compliant with REACH environmental regulations (EC 1907/2006) regarding substance restrictions. Designed specifically for M3 screw sizes in metric fastening systems.
