<p>The nut (6), particularly welded nut has a threaded bore of the nut in a condition, where the nut is not connected with a construction unit, and has an inserted cylindrical plug, which is filled from a flexible material, and has a defined diameter and a defined length. The diameter of the plug in a relaxed condition of the plug is larger than the diameter of the threaded bore, and finds itself outside of the threaded bore. Independent claims are also included for the following: (1) a method for production of a paint-finished metal construction unit (2) a method for production of a plugged nut.</p> |
