Professional Applications & Engineering Value

These zinc-plated steel flat washers deliver critical engineering solutions for industrial applications requiring durable load distribution and corrosion protection. The precisely engineered 0.656" inner diameter and 2.25" outer diameter create an optimal bearing surface that prevents fastener embedding and material deformation under heavy loads. The zinc-plated finish provides essential galvanic protection in environments exposed to moisture, chemicals, and temperature variations, significantly reducing maintenance frequency and replacement costs. Engineered specifically for 5/8" screw applications, these industrial washers maintain joint integrity in heavy machinery, structural steel connections, and manufacturing equipment where vibration resistance and long-term reliability are paramount. The inch system compatibility ensures straightforward integration into North American industrial standards and existing equipment specifications.
