How to choose self-tapping screws
The choice of a self-tapping screw depends on the material in which the fastening is performed and the operating conditions. For wood, it is better to order products with a large thread pitch and a sharp tip - they fit tightly into the material without splitting it. For metal, self-tapping screws with fine threads and a drill-shaped end that provides reliable fixation without a preliminary hole. If you need to fix drywall, choose lightweight concealed self-tapping screws with a phosphate coating that is resistant to moisture. For universal work, galvanized models that do not rust and retain their appearance when used outdoors are suitable.
It is also important to consider the length - the self-tapping screw must fit into the base by at least two thirds of its length. Pay attention to the shape of the head: the countersunk one sinks into the surface, and the semicircular one is suitable for decorative mounting.
