Clinserts are installed in alloys, lightweight materials, steel, and cast iron to strengthen threads in these substrates.

They’re also ideal for thread repair when a damaged thread needs to be restored to the same nominal diameter. Clinserts are commonly available in stainless steel and are supplied with 2 or 4 pre-assembled Clins, depending on the size. Once installed, the Clins expand into the parent material, creating a form-locking connection. Because of the Clins, checking the thread in that area with a DIN-standard thread gauge is not possible.

The Clins provide a positive lock against rotation and vibration, delivering high-strength joints even in lower-strength base materials. Typical applications include transmission housings, electronic equipment, and suspension components.

Clinserts are available in four main families:

  • Miniature Clinserts

  • Lightweight Clinserts

  • Heavy Duty Clinserts

  • Extra Heavy Duty Clinserts

Each Clinserts insert is offered in two versions:

  • Standard version

  • Locking version

Every Clinserts type has its own installation tool kit. Kits include the required tooling and a defined quantity of inserts, and complete tooling sets are also available that include all necessary installation tools.
