PRODUCTS

Blind rivet nuts with round shank
Tubtara® open end rivet nuts are used to bring in a strong and reliable thread into thin or thick metal plates/profiles, composites, or plastics where thread forming is either not possible because the material is too thin/weak/brittle or too hard for thread forming. Rivet nuts from Tubtara® also can be used for on site repair and maintenance work.

Blind rivet nuts with closed end
Tubtara® closed end rivet nuts are used to bring in a strong and reliable thread into thin or thick metal plates/profiles, composites, or plastics where thread forming is either not possible because the material is too thin/weak/brittle or too hard for thread forming. The huge benefit of closed end rivet nuts is that they can ensure water/gas tightness up to IP67 and IP68.

Features

Special blind rivet nuts
Tubtara® special/customized rivet nuts are used to bring in a strong and reliable thread into thin or thick metal plates/profiles, composites, or plastics where thread forming is either not possible because the material is too thin/weak/brittle or too hard for thread forming. The rivet nuts can be individually adjusted to your application needs. Dependent on your application requirements, together with our knowledge and the R&D department of Tubtara® we can suit the needs of almost every application.
- increased torque to turn resistance
- spacer functions
- visual identification
- controlled deformation to fit into plastic and composite applications
- higher grip ranges
- high vibration resistance to secure the screw from not falling out
