Prerequisites Of Using The Self tapping screws

Before the self tapping screws are put to work, it is advised that there should be a hole drilled in the surface of the metal. Don’t forget to take help from http://tappex.co.uk/. This, however, is not a mandatory requirement but always helpful in the easy completion of the job because a pre-drilled hole will make sure that the screw that is being used will fit into the surface smoothly and it will fix into the position firmly. Always ensure that the drill that is going to be used to make the initial hole is smaller than that of the screw else the threads will lose their tight grip.
