Application: Threaded inserts, locked and self-locking, are joining elements for manufacturing high strength, wear-resistant, vibration proof and exchangeable screw attachments in materials with low shear strength or for repairing stripped and damaged threads in those materials. The threaded inserts have a locking device that prevents the unwanted unscrewing of the insert when loosening the screw connection. The locking of the screw connection against self-locking is accomplished by several deformed threads in the middle of the internal thread.
Threaded inserts are intended for installation in materials with shear strength ³ 260 N/mm2. when installed in materials with shear strength of 260 N/mm2 the minimum tensile strength of screw connection is 1100 N/mm2.
