Detailed description

 

HELICOIL® Plus thread inserts

Excessive bolting torque, corrosion and even wear – these and other reasons can lead to thread damage.
HELICOIL® Plus thread inserts were developed in a variety of designs, ensuring quick thread repair. The use of non-wearing HELICOIL® Plus thread inserts not only repairs threads but also increases thread load.

First, the faulty thread is drilled out and the new holding thread is tapped by means of a HELICOIL® Plus tap drill. The HELICOIL® Plus is then installed using the installation mandrel provided. Now, the tang is simply broken using the tang break mandrel and the new thread with the HELICOIL® Plus thread insert is ready to use.

RIVKLE® blind rivet nuts

RIVKLE® blind rivet nuts are used where threads are required on thin-walled components.
They also result in higher thread stability. Typical applications include car body sheets, number plate attachments and the repair of defective threads for motorcycle frames.

RIVQUICK® blind rivets

The RIVQUICK® blind rivet technology has proven to be a reliable method for the non-detachable joining of thin-walled components using blind rivets. It is also perfect for joining components that are only accessible from one side. No heat is generated during the installation of these blind rivets and there is thus no distortion. They can even be easily used in layered components.

Prior to setting
The blind rivet is inserted into the drill hole.


During setting
The rivet body forms a defined locking head.
The drill hole is filled in.


After setting
The rivet mandrel breaks off at a predefined position at a specific force. The remaining rivet nail is firmly locked in the rivet body.
