Welded nut with conical collar

摘要

The nut (1) incorporates at least one collar (4) surrounding a bore (3), and the collar dia. diminishes with its distance from the fastening part. The circumferential surface (7) of the collar can be brought into contact with an edge (10) of an opening (9) in the component (8). This contact region forms the welding zone. Pref. The collar is a frustum of a cone or a zone of a sphere. The collar is located coaxially with the bore of the nut. Both ends of the bore are surrounded by a collar. The angle between the face of the nut and the circumferential surface lies between 20 and 45 deg., and is pref. 35 deg. The nut is produced by a cold-forming process. Pref. The nut is appropriately aligned before the welding process.
