METHOD OF MAKING A THREADED INSERT ASSEMBLY AND PRODUCT

摘要

METHOD OF MAKING A THREADED INSERT ASSEMBLY AND PRODUCT A method of making a threaded insert assembly for sheet material wherein a threaded insert that is a single unitary element is installed in a closely fitting hole in the sheet material with its threads occupying the hole. The sheet material around the hole on the exit side of the material is then upset into the threads of the insert in order to hold it by its threads so that it is adjustable by rotation. An unthreaded tip effectively prevents removal of the insert by back-screwing.
