Self-tapping screws are used in construction and manufacturing. They come in different head designs and are used for sheet metal, wood, and steel applications. They drill through objects and create a tight bond with the material. Flat head self-tapping wood screws are best for deck construction.

There are many types of screws used in construction and manufacturing today. A self-tapping screw is a special screw design that has self-drilling characteristics. These screws are used in sheet metal, steel and wood. The advantage of a self-tapping screw is that the hole does not require pre-drilling before the screw can be used.
A self-tapping sheet metal screw is designed to secure objects to sheet metal. Sheet metal is typically used in airplanes, automobiles, metal tables, and shelving. The self-tapping screw works best for sheet metal because the design of the screw has the effect of pulling the metal tightly to the head.

The self-tapping screw is available in different head designs. These include flat head, flat head, round head, hex head and oval head. Head design is an important aspect for specific applications.
The flat head self-tapping screw is a screw design that has a flat, flush head. This type of head design ensures that the screw does not protrude above the fixed object. The flat head screw usually requires a Philips screwdriver.

A self-tapping wood screw is a screw designed to fasten objects to wood. Some applications that require a self-tapping wood screw include shelving, furniture, and decks. These screws are unique because they can be used to drill into wood objects without causing a split in the material.

Using a flat head self-tapping wood screw is considered best practice for deck construction. These screws typically work more effectively than nails. The screws create an extremely tight connection between the deck planks and the floor joist, which can reduce the warping effect of wooden decks. These screws are also used in deck rails because they have the ability to connect thin rails without splitting the wood.

The thread design of a self-tapping screw is angled and angled. This pitch design forces the screw to drill through objects. Regular screws are smooth and require a nut to tighten.
The threaded screw is available in two formats. These are models of self-tapping or self-tapping screws. The thread cutting design is intended to remove material as it is being drilled. A self-tapping screw is more difficult to remove because it creates a tighter bond with the material.

Threaded screws can also be used in steel applications. Steel screws are typically required in heavy equipment and tooling applications. These tools are connected with special steel versions of threaded screws. Many automotive running boards are connected with steel screws.
