What is a hollow screw?

A hollow screw is a type of fastener that has a hollow core, allowing for other objects to pass through it. This versatile component has a wide range of applications in various industries, from construction to aerospace. In this article, we will explore the characteristics, uses, and benefits of hollow screws. We will also discuss the different types of hollow screws and their specific applications.

Characteristics of Hollow Screws

Hollow screws are typically made of metal, such as stainless steel, aluminum, or titanium. They are commonly produced using a combination of machining and threading processes. The hollow core of the screw is achieved by drilling or machining a hole through the center of the shaft. This design allows for the passage of wires, cables, or other fasteners through the screw, making it an essential component in various systems and structures.

The threads on a hollow screw may be internal or external, depending on its intended application. Internal threads allow for the screw to be screwed onto a threaded shaft or rod, while external threads enable the screw to be inserted into a pre-threaded hole. The choice of thread type depends on the specific requirements of the application.

Hollow screws come in a variety of sizes, with different thread pitches and lengths to accommodate diverse needs. They can also be manufactured with various head types, such as flat, pan, round, or hexagonal, depending on the specific installation requirements. Additionally, some hollow screws feature a shoulder or shank that provides added strength and stability in certain applications.

The unique design of hollow screws makes them suitable for a wide range of applications, from fastening electronic components to securing mechanical connections. Their hollow core allows for the passage of wires, cables, or other fasteners, making them an ideal choice for projects that require multiple components to be interconnected. Their durability and resistance to corrosion make them suitable for use in harsh environments, such as marine or outdoor applications.

Uses of Hollow Screws

Hollow screws are commonly used in the construction industry for securing electrical components, such as junction boxes, light fixtures, and conduit straps.
