💡 What is a wave washer used for in mechanical assemblies and how does the three-wave design benefit load retention?

Wave washers act as compact springs that maintain preload and resist loosening in tight spaces. Handy for sealing and vibration control in mechanical joints.

- Provide axial preload in confined areas - Absorb small movements to keep fasteners tight - Improve seal integrity in gear and equipment assemblies - Reduce loosening caused by vibration in machinery ✝️
