Self Tapping Screws
Self Tapping Screws
At a glance self tapping screws are similar spring nut screws (see later on this page for details). They are in fact different but are often regarded as interchangeable by mechanics and were sometimes likewise by the factory, so mechanics have a good excuse. Self tapping screw threads are sharp and cut a very coarse thread through sheet metal, plastics, etc. They are ideal partners for nylon Lokut nuts (see later). See Machine Screws for screwdriver type explanation.
