Key Features & Benefits at a Glance
- Superior corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in humid or chemically aggressive environments.
- Precise dimensional fit with 0.149" ID and 0.625" OD, providing accurate alignment and load distribution for No. 6 screws.
- Consistent performance due to uniform thickness (0.024-0.038"), preventing loosening and maintaining joint integrity under vibration.
- Environmental compliance assurance with RoHS 3 and REACH adherence, meeting strict international regulatory standards for industrial use.
- Broad compatibility with inch-system fasteners, simplifying sourcing and integration into existing North American assemblies.
- Durable material properties offering excellent strength-to-weight ratio without requiring additional surface treatments.
Professional Applications & Engineering Value
This 18-8 stainless steel flat washer delivers critical engineering solutions where corrosion resistance and dimensional precision are paramount. The inch system specification ensures seamless integration with No. 6 screw assemblies across industrial machinery, electrical enclosures, and marine equipment. Its flat washer design effectively distributes clamping force, preventing surface damage and maintaining bolt preload in high-vibration applications. The stainless steel composition eliminates galvanic corrosion risks when paired with compatible fasteners, while the precise 0.149" ID prevents misalignment during automated installation. These characteristics make it ideal for industrial washers applications demanding repeatable performance and regulatory compliance.
