LBTEK coaxial rod adapter has a stud at one end and a blind hole with an inner diameter of Ø6 mm at the other end, available in three depths. It comes in two types: 4-40 stud and M3 stud, compatible with components featuring 4-40 or M3 internal threads, suitable for connecting Ø6 mm coaxial rods. A side M3 set screw is provided to secure the Ø6 mm coaxial rod. A Ø1.8 mm through hole on the side allows for a 1.5 mm hex key to provide reinforced connection through the hole. When connecting coaxial system components with threaded holes on both ends, screw the coaxial rod adapter onto one component, screw one end of the coaxial rod into the other component, and insert the other end into the coaxial rod adapter to achieve coaxial series connection.
