S-90881A115 1.265" ID x 1.625" OD Wave Spring Lock Washers

Key Features & Benefits at a Glance

• Superior vibration dampening through wave spring design prevents fastener loosening in high-motion environments
• Exceptional corrosion resistance with 18-8 stainless steel construction for extended service life in harsh conditions
• Optimized load distribution across 1.625" OD surface area reduces stress concentrations on mating surfaces
• Consistent spring performance maintained by Rockwell C45 hardness rating for reliable tension retention
• Precision dimensional fit with 1.265" ID ensures perfect compatibility with 1 1/4" fasteners
• Minimal space requirement with compact 0.125" overall height profile for constrained assembly applications
• Global regulatory compliance with RoHS 3 and REACH standards for international industrial deployment

Professional Applications & Engineering Value

This 18-8 stainless steel wave washer delivers critical engineering solutions where vibration management and corrosion resistance are paramount. The wave spring configuration provides continuous axial force that compensates for thermal expansion, wear settlement, and dynamic loading conditions common in industrial machinery, automotive assemblies, and marine equipment. With its Rockwell C45 hardness, this wave washer maintains consistent spring characteristics under repeated compression cycles, preventing fatigue failure in high-cycle applications. The 1.265" ID ensures precise fitment with standard 1 1/4" screw sizes, while the corrosion-resistant properties of 18-8 stainless steel make it ideal for chemical processing, food manufacturing, and outdoor applications where moisture and corrosive elements would degrade inferior materials.
