A hollow screw bolt is a specialized type of screw that has a hollow center. This allows the screw to be threaded onto a bolt or threaded rod, providing a secure and adjustable connection. Hollow screw bolts are commonly used in construction, manufacturing, and mechanical applications, where they provide a convenient and flexible connection between different components. They can be used to secure panels, brackets, and other types of components in place, while still allowing for adjustments and fine-tuning of the position. Hollow screw bolts are typically made from materials such as steel, brass, or aluminum, depending on the specific application and requirements. They may be coated with a layer of zinc, chrome, or other materials to provide additional corrosion resistance or aesthetic appeal.

The size and configuration of hollow screw bolts can vary depending on the specific application. They may have different thread sizes and pitches, head types, and lengths to suit different types of bolts or threaded rods. Overall, hollow screw bolts are a versatile and useful component in many different types of applications, providing a secure and adjustable connection between different components. They offer a convenient and flexible solution for connecting panels, brackets, and other components, and are commonly used in construction, manufacturing, and mechanical applications.
