S-92161A022 0.127" ID x 0.25" OD Wave Spring Lock Washers

Key Features & Benefits at a Glance

• Superior vibration damping with wave design that maintains consistent spring tension under load, preventing fastener loosening in dynamic applications.
• Excellent corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in humid or chemically aggressive industrial environments.
• Precise dimensional compatibility with 0.127" ID and 0.25" OD engineered specifically for No. 4 screws, providing secure fit and optimal force distribution.
• Minimal space requirement with ultra-thin 0.005" thickness, ideal for compact assemblies where traditional spring washers cannot fit.
• Enhanced load distribution through wave-form geometry that compensates for thermal expansion and component wear in mechanical systems.
• Regulatory compliance assurance meeting RoHS 3 and REACH standards, making them suitable for regulated industries and international supply chains.
• Durable performance maintaining spring characteristics through repeated compression cycles without permanent deformation.

Professional Applications & Engineering Value

This 18-8 stainless steel wave washer addresses critical engineering challenges in precision assemblies requiring reliable spring tension and vibration resistance. The wave-form geometry provides continuous axial load compensation, solving common issues like fastener loosening in electrical enclosures, small machinery, and instrumentation panels where No. 4 screws are prevalent. Manufactured from corrosion-resistant stainless steel, these washers maintain performance in demanding environments where moisture or chemicals would degrade ordinary spring washers. The precise 0.127" ID and 0.25" OD dimensions ensure perfect compatibility with standard No. 4 screw sizes while the 0.005" thickness makes them ideal for space-constrained applications. This combination of precise dimensions, material durability, and wave-spring functionality delivers exceptional value for engineers seeking to improve assembly reliability and service life.
