The insert without a tang – HELICOIL® tangfree
Unlike HELICOIL® classic and HELICOIL® plus the HELICOIL® tangfree product has a driving notch at both ends of the insert rather than the conventional tang.
Characteristics
Function
With a drive notch instead of a tang, the insertion tool has a spring loaded pawl that engages with the notch and allows it to be installed into the threaded hole.
The new HELICOIL® tangfree product is manufactured by a different process, ensuring symmetry at both ends of the insert, therefore guaranteeing ease of insertion and a significant reduction in waste.
Benefits
- After installation there is no tang to remove
- Perfect symmetry allows easy installation from either end
- Corrosion and heat-resistant
- Wear-free
- Uniform load and stress distribution
- Available in different variants for very different requirements
- Assembly systems, tools, and products available from one source
HELICOIL® thread inserts are available in metric dimensions.
Versions
free running
Every thread of the thread insert with precision formed, rhombic
profile is free running. The result is an internal thread true to gauge
that can be used on both sides.
Our
seal of quality, a rhombic imprint at the end of the last thread,
unmistakably identifies each Böllhoff HELICOIL® tangfree free running as an
original Böllhoff product.
screwlock
The HELICOIL® tangfree screwlock bears the same benefits regarding threads as the HELICOIL® tangfree free running.
In addition, an integrated screw-locking area serves as a screw lock.
Locking
of the screw is achieved by one or several polygonal-shaped threads
that clamp the flanks of the screwed-in screw. The result is an
elastically resilient frictional locking.
The HELICOIL® tangfree screwlock can be recognised thanks to its red colour.
The HELICOIL® tangfree screwlock inserts can only be used with screws of property class 8.8 or higher.
