Professional Applications & Engineering Value
This aluminum flat washer delivers critical engineering solutions where corrosion resistance and weight reduction are paramount. The precisely engineered 0.406" inner diameter ensures perfect fitment for 3/8" screw applications, eliminating play and maintaining alignment in vibrating assemblies. The 0.875" outer diameter provides optimal surface coverage, distributing clamp load effectively to prevent material deformation in industrial washers applications. With Brinell 120 hardness, these precision washers maintain structural integrity in mechanical systems, electrical enclosures, and transportation equipment where aluminum's non-magnetic properties and environmental compliance are essential for modern manufacturing requirements.
Specification Summary & Compliance
Manufactured to inch system standards with critical dimensions: 0.406" inner diameter, 0.875" outer diameter, and thickness ranging 0.052-0.072".
