When to Use a Conical Washer: Top Use Cases Explained

Wondering when it’s best to use a conical washer over flat or lock washers? If your application involves vibration, frequent thermal changes, or uneven surfaces, conical spring washers are your best bet. They maintain bolt tension, reduce stress cracks, and improve safety in mission-critical systems.

Industries like automotive, aerospace, and construction rely heavily on conical spring washers in applications like engine assemblies, structural fastenings, and sensitive electronics. Their ability to maintain preload and resist loosening makes them indispensable in environments where failure isn't an option.
