KVT-Fastening has decades of experience with selling standard TUBTARA® blind rivet nuts. New developments and new designs are continually giving us more possibilities to offer special designs.

The three following areas illustrate the extensive range of possibilities for solving your particular application.

Die drei folgenden Bereiche zeigen die vielfältigen Lösungsmöglichkeiten für Ihre Anwendung auf.

Form:                  

A wide variety of shapes can be produced by modifying the manufacturing tools.

Examples:

1. 1. Flat head with centring

2. 2. Flat head with a sealing ring

3. 3. Special twist restraint "Anti-Turn"                

1. 4. Deep head as a spacer

Materials:

The standard materials are aluminium, steel and stainless steel of types 1.4567 (304/A2) and 1.4678 (316/A4).
On request we can quote you for critical environments containing chlorine or for instance for tunnel construction cold-formed stainless steel of types 1.4571 (316Ti / A5) or 1.4539 (904L / A6).

Steel coating:

Apart from the standard coating "Zinktop", which offers very good durability, further varieties are also available.

• One example is the coating "Ultra 1000" which compared with the traditional "Zinktop" coating gives at least twice the resistance to red rust formation in salt spray testing.
  (Details of resistance will be found in the brochure).
