S-96982A142 8.1 mm ID x 14.8 mm OD DIN 128A Split Lock Washers

Key Features & Benefits at a Glance

• Exceptional vibration resistance thanks to the curved spring design that maintains constant tension under dynamic loads
• Superior corrosion protection provided by zinc yellow-chromate plating, extending service life in harsh environments
• Reliable spring performance ensured by Rockwell C44 hardness, preventing permanent deformation under pressure
• Precise M8 screw compatibility with 8.1mm inner diameter for secure fit and optimal load distribution
• Industry-standard compliance with DIN 128A specifications, guaranteeing consistent quality and interchangeability
• Optimized space utilization with compact 14.8mm outer diameter and 2.5mm overall height for confined assemblies
• Enhanced fastener security through the split lock design that prevents loosening in high-vibration applications

Professional Applications & Engineering Value

This M8 split lock washer delivers critical engineering value in applications where vibration-induced loosening compromises assembly integrity. The curved spring design creates continuous axial pressure that counters rotational forces, while the zinc yellow-chromate plated steel construction provides dual protection against corrosion and wear. Engineers specify this DIN 128A certified component for automotive subassemblies, industrial machinery, and electrical enclosures where metric fasteners require maintained clamping force. The combination of Rockwell C44 hardness and precise dimensional control ensures consistent performance in temperature-cycling environments, making it ideal for OEM and MRO applications demanding reliable vibration resistance without frequent retightening.
