scope:

APPLICATION: Thread inserts with ring lock are joining elements for manufacturing high strength, wear-resistant, vibration proof and exchangeable screw attachments in metallic and non-metallic materials of low shear strength, or for repairing stripped and damaged threads in those materials. The thread inserts have a locking device that prevents the unwanted unscrewing of the insert, i.e. while loosening the screw connection or due to vibration. The locking of the screw connection against self-loosening is accomplished by several deformed threads which are located in the middle of the insert.
