Professional Applications & Engineering Value

This brass flat washer delivers critical engineering solutions where corrosion resistance and electrical conductivity are paramount. The copper alloy construction prevents galvanic corrosion when used with No. 8 screws in marine, plumbing, and electrical enclosures. Its Rockwell B60 hardness maintains structural integrity under repeated torque cycles, while the precise inch system dimensions ensure perfect alignment in industrial washers applications. The flat profile distributes clamping force evenly, protecting soft materials and preventing joint failure in vibration-prone assemblies.
