Professional Applications & Engineering Value

Engineered for demanding industrial washers applications, this brass flat washer solves critical challenges in corrosion-prone environments where steel components would degrade rapidly. The Rockwell B60 hardness provides optimal balance between malleability and strength, preventing deformation under high clamp loads while maintaining seal integrity. Its precise 0.5" ID ensures perfect alignment with 7/16" screw fasteners, eliminating micro-movement that causes wear in vibrating machinery. The corrosion resistant brass material makes it ideal for marine equipment, plumbing systems, and electrical enclosures where galvanic corrosion must be prevented. With inch system compatibility, these precision washers deliver consistent performance in North American industrial maintenance and OEM assembly lines.
