A specialized forming solution for producing consistent tailless threaded inserts used to reinforce and repair internal threads.
The Tailless Screw Sleeve Coiling Machine is designed for manufacturing tangless wire thread inserts, also known as tailless screw sleeves. These helically coiled inserts are installed in tapped holes to strengthen internal threads, improve wear resistance, and support repeated fastener assembly.
The machine forms suitable profiled wire into accurately controlled helical coils. Its adjustable forming system supports consistent insert diameter, pitch, coil count, and overall length within the applicable production range.


Core Features
Typical Applications of Finished Inserts
Material and Product Compatibility
The machine can be configured for suitable profiled spring wire used in tailless threaded inserts. Material compatibility depends on the wire profile, material properties, nominal thread size, insert type, and required end geometry.
Please provide your wire information and finished insert drawing for technical evaluation.
Tailless inserts require controlled helical forming and consistent end geometry to support installation without a conventional break-off tang. The machine is configured around the insert drawing and wire profile, helping manufacturers produce repeatable coils for thread reinforcement and repair applications.
