Self-Tapping Screw A self-tapping screw is a type of fastener that has a special design enabling it to create its own threaded hole as it is driven into a material. Unlike traditional screws that require a pre-drilled pilot hole, self-tapping screws have a cutting edge or a sharp point that allows them to tap into the material and form threads. This feature makes them particularly useful in applications where it may be challenging or impractical to create a pilot hole beforehand.
When using self-tapping screws, it's important to choose the right type and size for the specific application and material. Additionally, care should be taken not to overtighten the screws, as this can compromise their effectiveness. Proper selection and installation are crucial to ensure the integrity of the connection.

Self Tapping Screws are a type of fastener, in some ways similar to a bolt, typically made of metal, and characterized by a helical ridge, known as a male external thread. Self Tapping Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out. There are many Self Tapping Screws for a variety of materials; those commonly fastened by Self Tapping Screws include sheet metal, wood, and plastic.
Zinc and Chromate Self Tapping Screws: Silvery and offers resistant to corrosion for Self Tapping Screws.
Plain Finish Self Tapping Screws: Self Tapping Screws with No Coating.
Zinc Plated Self Tapping Screws: Self Tapping Screws Coated with Zinc.
Zinc and Yellow Chromate Self Tapping Screws: Offers better resistant to corrosion to Self Tapping Screws than Chromate.
Hot Dipped Galvanized(HDG) Self Tapping Screws: Offers superior resistant to corrosion due to the dipping of Self Tapping Screws in the molten zinc.
