As technology moves forward, customer expectations and demands for higher quality fasteners is at an all time high. Tangless CoilThread inserts revolutionized the industry with the introduction of the Tangless screw thread insert, the most advanced helically coiled screw thread insert in the market today.

Tangless CoilThread inserts are a continuous, helically-coiled, bi-directional, wire design. This innovative design allows for installation using a drive notch located at each end of the coil insert instead of a tang located at one end of the insert.

Because Tangless inserts have a notch at both ends, this eliminates the need to orient the insert during installation and saves on production cost. But that's not all...

Once installed, Tangless insert are identical in form, fit, and function to conventional tanged inserts (CoilThread, Heli-Coil, Recoil, etc.), and install into the same STI tapped holes.

In order for male threaded fasteners to properly be positioned into tanged inserts, the tangs have to be broken off. This increases total installation time and requires additional tooling, thus, resulting in higher installation cost. With Tangless CoilThread inserts this process is completely eliminated resulting in lower installation cost per hole.

In applications that require blind holes, tanged inserts require additional space below the insert in order to break-off the tang and not damage the parent material. When using Tangless CoilThread inserts the space between the insert and the bottom of the hole is greatly reduced. This leads to a reduction in size and weight of machined parts. Tangless CoilThread inserts are FOD-Free by design, so contamination from missed tangs is not possible.
