Sheet Metal Screws are screws designed to fasten thin metal sheets (sheet metal) and are primarily used in automobiles, construction, home appliances, and more. These screws create and secure holes by being directly screwed into the sheet metal. In some cases, pilot holes may be drilled, but self-tapping types that do not require a pilot hole are generally more common.

Overview of Sheet Metal Screws

Main Features

Sheet metal screws are designed with a sharp tip and deep threads, allowing them to easily penetrate thin metal sheets. To enhance durability and rust resistance, they are often made of zinc-plated or stainless steel materials. Additionally, they are designed to resist loosening, making them highly resistant to vibrations and impacts. Common screw heads include flat head and truss head, selected based on the application.
Self-tapping function eliminates the need for pilot holes.
Anti-rust processing (such as zinc plating and stainless steel materials) improves durability.
Provides strong fastening power resistant to vibrations and impacts.

Main Applications

The primary role of sheet metal screws is to securely fasten thin metal sheets to each other or to other materials such as plastic or wood. With their self-tapping ability, they create holes while fastening, simplifying the assembly process. This significantly improves work efficiency.

Role of Sheet Metal Screws

Role in Assembly

Sheet metal screws not only firmly secure metal sheets but also streamline the assembly process by performing drilling and fastening simultaneously. They also provide high durability in environments subject to frequent vibrations and impacts, ensuring stability after assembly. Furthermore, when pilot holes are unnecessary, they contribute to reducing assembly costs.

Main Types

Sheet metal screws come in various types, including tapping screws and self-drilling screws (drill screws), chosen based on the application and environment. They are available in different shapes such as flat head, truss head, and rust-resistant variants.
– Tapping Screws
Directly screwed into sheet metal.

– Self-Drilling Screws (Drill Screws)
Drill-shaped tip eliminates the need for a pilot hole.

– Flat Head Screws
Ideal for applications requiring a flush finish.

– Truss Head Screws
Ensures stability with a broad contact surface.

– Rust-Resistant Screws
Processed for use in outdoor or high-humidity environments.
