S-97527A001 0.146" ID x 0.569" OD Internal-Tooth Lock Washers for Soft Material

Key Features & Benefits at a Glance

• Superior vibration resistance with internal teeth that bite into mating surfaces to prevent loosening under dynamic loads
• Enhanced corrosion protection through zinc-plated steel construction for extended service life in industrial environments
• Precision dimensional control with 0.146" ID and 0.569" OD ensuring perfect fit for No. 6 screw applications
• Exceptional mechanical strength backed by Rockwell C44 hardness rating for reliable performance in demanding applications
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use
• Consistent thickness tolerance (0.023-0.027") providing uniform clamping force and seating performance
• Internal tooth configuration offering concentrated locking action while protecting visible surfaces from damage

Professional Applications & Engineering Value

This internal tooth lock washer delivers critical vibration-resistant fastening for machinery, equipment assemblies, and automotive components where dynamic loads threaten joint integrity. The zinc-plated steel construction provides dual protection against corrosion while maintaining the Rockwell C44 hardness necessary for repeated disassembly cycles. The precisely engineered internal teeth concentrate locking force directly under the fastener head, eliminating the need for additional locking mechanisms and reducing assembly time. Engineered specifically for No. 6 screw size applications in the inch system, this washer solves common industrial challenges including fastener loosening, surface damage prevention, and maintenance of consistent clamping force in high-vibration environments.

Specification Summary & Compliance
