Spring washer for Favelle Favco

The AFSM-1200-0X02 spring washer is an M12 component engineered to provide elastic preload force within a bolted connection. By maintaining consistent tension on the bolt and nut, this washer compensates for material settling and prevents the loosening of fasteners caused by vibration, thermal expansion, or dynamic operational loads. It is used in critical structural connections, slewing mechanisms, and hoisting systems where fastener security is required.

This component is compatible with Favelle Favco crane machinery. The M12 specification indicates it is sized for use with 12 mm metric bolts. Proper installation of these washers ensures that the joint remains secure during the repetitive movements and heavy lifting cycles typical of tower crane operations.

Spring washers function by exerting a reaction force when compressed, which keeps the fastener assembly under tension and prevents the nut from rotating freely. In heavy machinery, these components are used to ensure that structural and mechanical joints remain tight, supporting the overall integrity of the equipment during operation.
