Professional Applications & Engineering Value

These No. 12 brass flat washers deliver exceptional engineering value through their corrosion-resistant brass construction and precise dimensional specifications. The 0.228" inner diameter ensures perfect alignment with No. 12 screws, eliminating play and vibration-induced failures in critical assemblies. The 0.5" outer diameter provides maximum surface coverage, distributing clamp load effectively to prevent material deformation and joint fatigue. Particularly valuable in electrical applications and marine environments where brass's non-sparking and anti-corrosive properties are essential, these inch-system washers solve common industrial challenges of galvanic corrosion and component degradation. The controlled thickness range accommodates manufacturing tolerances while maintaining consistent pressure distribution across fastened surfaces.

Specification Summary & Compliance
