Here are some key features and considerations for threaded bushes:

• Internal and External Threads: The threaded bush has both internal threads (inside the cylindrical hole) and external threads (on the outside surface). These threads match the size and pitch of the screws or bolts intended for use.
• Material: Threaded bushes can be made from various materials, including brass, stainless steel, aluminum, or other alloys. The choice of material depends on factors such as the application environment and the required strength.
• Installation: Threaded bushes are typically press-fit or threaded into a pre-drilled hole. The installation process may involve using a tool to thread the bush into the material.
• Applications: Threaded bushes are used in a variety of applications, including woodworking, metalworking, plastic molding, and other industries where a secure threaded connection is needed.
• Repair and Reinforcement: One common use of threaded bushes is to repair or reinforce threads that have become damaged or worn. By providing a new threaded surface, the integrity of the connection can be restored.
• Types and Styles: There are various types and styles of threaded bushes, including straight-shank, flanged, and key-locking designs. The choice depends on the specific requirements of the application.
• Thread Size and Pitch: When selecting a threaded bush, it's crucial to match the thread size and pitch with the fasteners that will be used. This ensures a proper and secure fit.
