Easy installation – HELICOIL® plus

HELICOIL® plus has a reduced diameter first coil ensuring easy installation without the need for pre-winder tooling.

Characteristics

Function

HELICOIL® plus thread inserts

HELICOIL® plus has a reduced diameter first coil allowing it to be screwed into the hole without the need for prewinding and this simplifies the tooling significantly and makes it simpler and quicker to install. Once installed it provides very similar tensional strength to the classic insert.

Benefits

  • Corrosion and heat-resistant
  • Wear-free
  • Reject recovery
  • Uniform load and stress distribution
  • Easy identification even when installed (colouring or surface treatment)
  • Available in different variants for very different requirements
  • Assembly systems, tools, and products available from one source

HELICOIL® thread inserts are available in metric and imperial dimensions.

Versions

free running

HELICOIL® 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.

The green colour allows easier identification when the HELICOIL® free running is installed.

Our seal of quality, a rhombic imprint at the end of the last thread, unmistakably identifies each Böllhoff HELICOIL® free running as an original Böllhoff product.

screwlock

HELICOIL® screwlock

The HELICOIL® screwlock bears the same benefits regarding threads as the HELICOIL® 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® screwlock can be recognised thanks to its red colour.
The HELICOIL® screwlock inserts can only be used with screws of property class 8.8 or higher.
