What Are The Types Of Threaded Sleeves

There are many types of threaded sleeves, and according to different classification standards, there can be the following main types:
Classified by application scenario:
Internal hexagonal threaded sleeve: suitable for connecting hexagonal screws and nuts, commonly used in mechanical, machine tool and other fields.
Inner hexagonal ball head threaded sleeve: With a ball head design, it is more convenient to adjust the connection angle during connection and reduce thread wear.
External hexagonal threaded sleeve: suitable for connecting external hexagonal screws and nuts, commonly used in fields such as automobiles and electric tools.
Button type threaded sleeve: With an operable button, it can quickly install and remove nuts, suitable for frequent disassembly occasions.
Steel bar sleeve: also known as straight threaded steel bar connector or steel bar connector, mainly used for mechanical connection of steel bars.
Classified by structural characteristics:
Straight threaded sleeve: a steel sleeve used for mechanical joints of steel bars to transmit axial tension or pressure, usually used for connecting steel bars.
Conical thread sleeve: It is another type of sleeve used for connecting steel bars, with a specific thread shape.
Squeeze sleeve: suitable for squeezing and connecting steel bars.
Classified by other specific attributes:
Cold extrusion sleeve: A specific type of steel reinforcement sleeve.
Positive and negative thread sleeve: A sleeve with both positive and negative threads, used for special connection needs.
Welding sleeve: a sleeve that can be connected by welding.
Variable diameter sleeve: used to connect steel bars or screws of different diameters.
When selecting threaded sleeves, it is necessary to comprehensively consider factors such as specific application scenarios, working conditions, load requirements, and costs. At the same time, it should be ensured that the selected sleeve complies with relevant standards and specifications to ensure the safety and reliability of its connection.
