Professional Applications & Engineering Value
This aluminum flat washer delivers critical engineering solutions where corrosion resistance and weight reduction are paramount. The Brinell 95 hardness ensures reliable performance in demanding applications including machinery assembly, electrical enclosures, and transportation equipment. Its precise 0.515" ID provides secure seating on 1/2" screws while the 0.875" OD distributes clamping force effectively, preventing surface indentation and maintaining joint integrity. The aluminum construction naturally resists galvanic corrosion, making it ideal for outdoor installations, marine environments, and chemical processing facilities where steel washers would degrade prematurely.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with 0.515" inner diameter and 0.875" outer diameter, this flat washer maintains consistent 0.059-0.069" thickness for uniform performance. The aluminum material with Brinell 95 hardness ensures mechanical reliability while complying with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Engineered for use with 1/2" screws, this component meets industrial standards for load distribution and corrosion resistance in critical assembly applications.
