S-91169A220 14.7 mm ID x 24.1 mm OD DIN 127B Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance prevents fastener loosening in high-stress applications, ensuring long-term joint integrity
• High-strength steel construction with Rockwell C44 hardness maintains spring tension and performance under extreme mechanical loads
• Precision DIN 127B dimensions (14.7mm ID × 24.1mm OD) ensure perfect fit and consistent performance with M14 fasteners
• Split lock design creates continuous spring action that compensates for thermal expansion and vibration-induced movement
• Full regulatory compliance with RoHS 3 and REACH standards eliminates chemical restriction concerns in global supply chains
• Optimized 2.8-3.2mm thickness provides ideal balance between spring force and installation clearance requirements
• Metric standard compatibility enables seamless integration with European machinery and equipment specifications

Professional Applications & Engineering Value

This M14 split lock washer delivers critical anti-loosening protection in demanding industrial environments where vibration and dynamic loads compromise fastener integrity. Manufactured from high-strength steel hardened to Rockwell C44, the DIN 127B standard split lock design generates continuous radial pressure that maintains clamp load despite thermal cycling and mechanical stress. The precise 14.7mm internal diameter ensures secure seating on M14 fasteners while the 24.1mm outer diameter provides optimal bearing surface. Engineering teams specify these metric lock washers for heavy machinery, automotive assemblies, and industrial equipment where vibration resistance is paramount to operational safety and maintenance intervals. The standard lock washer configuration offers reliable performance across temperature variations and load conditions without requiring special installation tools.
