Curved Spring Washer – Even Load Distribution & Anti-Loosening
Usage scenarios:
- Automotive and transportation: ideal for suspension components, engine mounts, and fasteners exposed to vibration where maintaining preload is critical.
- Industrial machinery and equipment: used in motors, gearboxes, pumps and assembly lines to prevent loosening from continuous vibration and shock.
- Construction, electronics and energy: suited for structural joints, electrical panels, rail and renewable-energy installations where even load distribution and thermal movement compensation are needed.
Product features
The curved spring washer is a durable, precision-formed washer designed to fit under the head of a fastener to increase the bearing surface and improve hold, offered in standard sizes and corrosion-resistant finishes. Its curved spring geometry delivers even load distribution and sustained axial tension, absorbing shock and resisting vibrational loosening to extend joint life and reduce maintenance. The shaped cross-section and spring-tempered construction create a reliable locking action that compensates for settling and maintains clamp force in demanding applications.
