Tangless Stainless Steel Wire Thread Inserts

Tangless Stainless Steel Wire Thread Inserts

Tangless inserts are easily adjusted or removed after initial installation. Technicians simply re-insert the installation tool and unwind the Tangless Thread Insert from its threaded hole. The tool never touches the application, ensuring no damage occurs; a big improvement over outmoded insert removal techniques. Eliminating loose tangs that can potentially damage the finished product improves throughput and reduces rework on your production line.


Without a tang to remove after insert is installed, a complete stage in the process is eliminated. There is no necessary vacuuming or tang extraction or the counting of displaced tangs to ensure none are left in the manufactured product. This is ideal for saving time during automatic installation in high volume applications. The Free Running Coil Threaded Insert bi-directional design also eliminates time-consuming insert checking prior to each installation.
