Professional Applications & Engineering Value

This M16 metric flat washer delivers critical engineering solutions through its black oxide steel composition and DIN 125 standardization. The precisely controlled 17mm inner diameter ensures secure seating on M16 screws and bolts, while the 30mm outer diameter provides optimal surface coverage to prevent embedding and distribute clamping forces evenly. The 2.7-3.3mm thickness range accommodates minor surface irregularities while maintaining consistent compression characteristics. These flat washers are particularly valuable in automotive subassemblies, industrial machinery, and construction applications where corrosion resistance and dimensional stability are paramount. The black oxide surface treatment creates a protective barrier against oxidation while maintaining electrical conductivity, making these components suitable for grounding applications and outdoor equipment exposed to moisture and temperature variations.
