Don't settle for anything less than the original...
Tangless Threaded Inserts have all the characteristics of Tanged Threaded Inserts but in addition, they eliminate tang break-off and retrieval and are easily adjusted or removed after installation.
Tangless Threaded Inserts reduce the time required for installation as removal of the tang is not required.
Installation requires the use of a special tool designed for Tangless Threaded Inserts that features a head
that grips and drives the Tangless insert into the hole. The bidirectional design of Tangless Threaded
Inserts eliminates the need to orient each part and saves time in applications that usually require counting
of each removed Tang.

How do they install without tangs?
Here's where Tangless CoilThread Inserts stand out from all other helically-coiled threaded inserts. Instead of a tang, these new inserts feature a unique, ramped driving notch on the inside diameter of the first coil on each end of the insert.
To drive the insert we developed on innovative installation tool with a patented, internal spring loaded pawl located at the tip of the tool's mandrel. During installation this hooked pawl locks into the insert Driving Notch and rotates the insert into the tapped hole, The pawl then retracts onto the mandrel to allow the tool back out of the installed insert.
Installation Process
The Installation Process Is Simple
- Partially thread an insert onto the tool's mandrel
- No need to orient the insert... they're bi-directional!
- Align the insert with the tapped hole and press the trigger on the electric installation tools
That's it! Everything else is automatic. The insert goes in, the tool comes out and the job is finished. There is no tang to break off. The insert is ready for a bolt or screw.
