S-90881A112 0.245" ID x 0.377" OD Wave Spring Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through wave design that maintains consistent spring force under dynamic loads
• Excellent corrosion resistance provided by 18-8 stainless steel composition for long-term reliability in harsh environments
• Optimal load distribution with precise 0.245" ID ensuring perfect fit for No. 12 screws
• Enhanced durability from Rockwell C45 hardness that withstands repeated compression cycles
• Space-efficient design with minimal 0.03" overall height for compact assembly applications
• Reliable performance maintained across temperature variations thanks to stainless steel thermal stability
• Global compliance assurance with RoHS 3 and REACH regulations for international supply chain integration

Professional Applications & Engineering Value

This 18-8 stainless steel wave washer delivers critical engineering solutions where vibration damping and spring tension maintenance are essential. The wave form geometry provides consistent axial force that compensates for thermal expansion, wear, and settling in assembled components. Manufactured from corrosion-resistant stainless steel, it performs reliably in demanding environments including electrical enclosures, automotive assemblies, and industrial machinery. The precise 0.245" inner diameter ensures perfect alignment with No. 12 screws, preventing installation issues while the Rockwell C45 hardness guarantees long-term performance without deformation. Ideal for applications requiring space-constrained spring force solutions where traditional coil springs cannot fit.
