• Heavy-duty application readiness with inch system specifications meeting industrial assembly requirements

Professional Applications & Engineering Value

This zinc-plated steel square washer delivers exceptional engineering value in industrial fastening applications where standard round washers fall short. The square configuration provides significantly larger bearing surface area, effectively distributing clamp load across wider surfaces to prevent material deformation and embedment in softer substrates. The zinc plating creates a protective barrier against oxidation and corrosion, making these washers ideal for outdoor equipment, electrical enclosures, and machinery exposed to humid conditions. Engineered specifically for No. 6 screw applications, the precise 0.156" inner diameter eliminates play and misalignment during assembly, while the 0.75" width offers superior stability in high-vibration environments. This combination of material properties and geometric design solves common industrial challenges including joint relaxation, surface damage, and corrosion-induced failure.
