- Exceptional durability with Rockwell C44 hardness rating for long service life in demanding applications
- Precise dimensional fit with 0.393" ID specifically engineered for 3/8" screws
- Optimal spring force distribution thanks to 0.07" overall height and wave configuration
- Reliable performance in high-stress environments using high-quality steel construction
- Environmental compliance meeting RoHS 3 and REACH standards for global industrial use
- Space-efficient design with minimal 0.007" thickness for compact assembly requirements
Professional Applications & Engineering Value
This steel wave washer delivers critical engineering solutions for industrial applications where vibration-induced fastener failure is a primary concern. The wave spring design creates consistent axial load that compensates for thermal expansion, material relaxation, and vibration stresses in machinery, automotive, and heavy equipment assemblies. With its Rockwell C44 hardness rating, this washer maintains structural integrity under repeated compression cycles, making it ideal for 3/8" screw applications requiring reliable, long-term fastening performance. The precise 0.393" ID and 0.5" OD dimensions ensure proper fit and function in tight-tolerance assemblies, while the steel material provides the necessary strength for high-load scenarios where plastic or softer metal washers would deform or fail prematurely.
Specification Summary & Compliance
This wave washer features precise inch measurements with 0.393" internal diameter, 0.5" outer diameter, 0.007" thickness, and 0.07" overall height, engineered for 3/8" screw size applications. Manufactured from high-grade steel with Rockwell C44 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental standards for industrial components.
