Retaining Ring DIN 984 Spring

The DIN 984 spring retaining ring features special lugs for a bore, which provide reliable engagement of the fastening elements. The lugs are bent to secure the fastener in place. The element prevents self-loosening of the fastener under dynamic loads.

This type of fastener is used in instrument making, machinery manufacturing, production facilities, and at service stations for repairing automotive and agricultural equipment. It is made of spring steel, which offers wear resistance, reliability and durability.

Due to the properties of the material, the lugs on the ring can be bent and unbent multiple times. Coated fasteners — with oxide or phosphate coating — have a longer service life. The ring is used together with bolts, wood screws and threaded studs of the corresponding diameter.
