Professional Applications & Engineering Value

This zinc-plated steel flat washer delivers critical engineering solutions where corrosion resistance and load distribution are paramount. The substantial 3" outer diameter creates an expanded bearing surface that effectively distributes clamping force, preventing material deformation in soft substrates and reducing stress concentration around 3/8" screw connections. The zinc plating provides sacrificial protection against oxidation, making these industrial washers ideal for outdoor equipment, structural assemblies, and machinery exposed to moisture or chemical environments. With precise 0.406" inner diameter tolerances, installers achieve consistent alignment while the controlled 0.051-0.080" thickness range accommodates varying gap requirements in construction, manufacturing, and maintenance applications.

Specification Summary & Compliance

Manufactured to standard inch system dimensions with 0.406" inner diameter and 3" outer diameter. Constructed from zinc-plated steel with thickness ranging 0.051-0.080" for 3/8" screw applications. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial markets.
