Professional Applications & Engineering Value

This M16 metric flat washer delivers critical engineering value in corrosive or high-moisture environments where standard washers fail. The 316 stainless steel material provides superior pitting and crevice corrosion resistance, making it essential for chemical plants, offshore equipment, and food processing machinery. Its flat washer design with precise 17.4mm ID and 55.5mm OD dimensions ensures uniform clamping force distribution across M16 bolted connections, preventing surface damage and maintaining joint integrity under vibration. This ASME B18.22M compliant component solves common industrial challenges of premature fastener failure and maintenance downtime, while REACH compliance addresses regulatory requirements for European market applications.

Specification Summary & Compliance

Manufactured to ASME B18.22M dimensional standards for metric flat washers with inner diameter of 17.4mm, outer diameter of 55.5mm, and thickness range of 3.5-4.6mm. This 316 stainless steel flat washer is compliant with REACH (EC 1907/2006) regulations regarding substance restrictions and is suitable for M16 screw applications requiring corrosion resistance and dimensional precision in industrial assemblies.
