S-95795A116 8.5 mm ID x 22 mm OD Internal / External-Tooth Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance with dual internal and external teeth that bite into mating surfaces, preventing loosening under dynamic loads
• Enhanced corrosion protection through zinc-plated steel construction, extending service life in harsh industrial environments
• Precise M8 compatibility with 8.5mm inner diameter ensuring perfect fit and uniform load distribution for fastener assemblies
• Reliable locking performance with 22mm outer diameter providing broad contact area for increased stability and reduced maintenance
• Durable material integrity from hardened steel base maintaining tooth sharpness and spring action through repeated use cycles
• Global compliance readiness meeting RoHS 3 and REACH standards for international supply chain integration
• Optimized thickness design (2.7-3.3mm) balancing clamping force with space constraints in compact assemblies

Professional Applications & Engineering Value

This M8 tooth lock washer delivers critical vibration damping in demanding applications where zinc-plated steel construction resists environmental degradation. The unique internal/external tooth configuration creates multiple biting points that mechanically lock fasteners against rotational loosening caused by machinery vibration or thermal cycling. Engineered for metric system compatibility, the washer maintains preload in automotive subassemblies, industrial equipment, and electrical enclosures where M8 fastener integrity is paramount. The dual-tooth design eliminates the need for additional locking mechanisms, reducing assembly time while providing heavy-duty reliability in high-cycle applications.

Specification Summary & Compliance

Manufactured to standard metric dimensions with 8.5mm ID and 22mm OD, this tooth lock washer maintains consistent thickness between 2.7-3.3mm for reliable performance. The product conforms to industry standards for internal/external tooth lock washers and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
