S-95795A114 5.3 mm ID x 18 mm OD Internal / External-Tooth Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance with dual internal/external 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 M5 compatibility with 5.3mm inner diameter ensuring perfect fit for standard metric fasteners
• Optimized load distribution from 18mm outer diameter providing stable bearing surface for connected components
• Reliable performance with 2.2-2.6mm thickness maintaining consistent clamping force in high-stress applications
• Dual-direction locking action where internal teeth grip the bolt while external teeth secure against the workpiece
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe global industrial use

Professional Applications & Engineering Value

This M5 metric tooth lock washer delivers critical vibration-resistant performance in demanding mechanical assemblies. The zinc-plated steel construction provides essential corrosion resistance for equipment exposed to moisture or harsh operating conditions. The unique internal/external teeth design creates a multi-directional locking mechanism that effectively counters rotational forces in automotive components, machinery, and electrical enclosures. Unlike standard flat washers, the dual-tooth configuration ensures maintained bolt preload in high-vibration environments, preventing costly downtime from fastener failure. The precise 5.3mm ID guarantees proper M5 screw alignment while the 18mm OD offers sufficient surface coverage for load distribution. This engineering solution addresses common industrial challenges of joint integrity and maintenance reduction in vibration-prone applications.

Specification Summary & Compliance
