Self drilling screws, self tapping screws, button head screws, and phillips truss head screws are all important components that help hold sheet metal, saw boards, and other objects together.

Self tapping screws are usually made of steel with a galvanized and passivated surface. These quick-install fasteners are useful and easy to use because they don’t require pre-tapping. Instead, first make the threaded bottom hole of the connected part, and screw the self-tapping screw into the threaded bottom hole of the connected part. This process makes self-tapping screws ideal for joining sheet metal, saw boards, and other objects.

Self drilling screws, on the other hand, are made of carburized steel, which is one of the most commonly used materials for its production. Such screws can also be made of stainless steel or other non-ferrous metals. However, all self-drilling screws must be heat treated to achieve the necessary mechanical and serviceability properties required by the standard. Carbon steel self-tapping screws must be carburized, while stainless steel self-tapping screws must be solution hardened.

Button head screws are similar to self-tapping screws and are designed to handle thin materials such as sheet metal, plastic, or fiberboard. Their low profile heads allow them to sit flush with the surface of the material, making them ideal for applications where aesthetics are important.

Finally, Phillips Truss Head Screws feature a unique button head design that is ideal for applications requiring a low profile. They are commonly used in computer cases and sheet metal assemblies where screws need to be hidden.
