Self Tapping Screw Tapped Screw Flat Head DIN 7982,A self-tapping screw is a type of fastener that can create its own threads as it is driven into a material. This means that a pre-existing hole is not necessary for the screw to be inserted. Instead, the screw’s sharp point and thread design allows it to cut through the material, forming threads as it goes.
Self-tapping screws are often used in situations where a strong connection is needed but there is no existing threaded hole in the material. They are commonly used in woodworking, metalworking, and plastic fabrication, as well as in automotive and electronics industries.
Self-tapping screws come in many different shapes and sizes, with different thread patterns and materials to suit different applications. Some self-tapping screws are designed to be used in soft materials such as wood or plastic, while others are meant for use in harder materials such as metal.
Overall, self-tapping screws are a useful and versatile type of fastener that can save time and effort in a wide range of applications.

Self-tapping screws have several features that make them useful for a wide range of applications. Some of these features include:
A tapered, pointed end: This allows the screw to “tap” its own threads as it is inserted into the material, eliminating the need for a pre-drilled hole.
Flutes or grooves: These run along the length of the screw and help to remove material as the screw is inserted, reducing the risk of the screw breaking or stripping the material.
Different thread patterns: Self-tapping screws can have different thread patterns, depending on the type of material they are intended to be used with. For example, a screw with a coarse thread pattern may be used with wood, while a screw with a fine thread pattern may be used with metal.
Different head types: Self-tapping screws can have different types of heads, such as flat, pan, or round. The choice of head type depends on the specific application and the desired appearance.
Corrosion-resistant materials: Self-tapping screws can be made from a variety of materials, including stainless steel, brass, or zinc-plated steel, to resist corrosion and improve durability.
Different lengths and diameters: Self-tapping screws are available in a range of lengths and diameters, making it possible to find the right screw for a particular application.
