Professional Applications & Engineering Value

This M16 flat washer solves critical engineering challenges in heavy machinery, structural steelwork, and industrial equipment assembly. The zinc-plated steel construction provides essential corrosion resistance while maintaining structural integrity under high compressive loads. With precision metric dimensions (17.3mm ID × 43.6mm OD) and controlled 3.0-4.0mm thickness, it prevents fastener loosening from vibration and distributes clamping force evenly across connected surfaces. The ASME B18.22M standard compliance ensures reliable performance in industrial washers applications where dimensional accuracy directly impacts assembly safety and maintenance intervals.

Specification Summary & Compliance

Manufactured to ASME B18.22M dimensional standards for metric flat washers. Features 17.3mm inner diameter, 43.6mm outer diameter, and 3.0-4.0mm thickness range compatible with M16 screw size. Constructed from zinc-plated steel with REACH (EC 1907/2006) compliance for 223 SVHC substances (as of 01/17/2022). Suitable for general industrial applications where corrosion resistance and standardized dimensions are required.
