Spin rivet nut onto simple hand or power tool, insert into pre-drilled or punched hole, set nut, withdraw tool mandrel - done. When load-bearing threads are required in thin walled materials or profiles, blind nuts are a most effective solution. They can be fitted "blind" (from one side only) with no re-machining/processing and without damage to pre-treated surfaces. Clufix® offers an extensive program and wide range of materials, head, or shank types as well as standard, medium, long, and extra-long grip lengths. Clufix® blind rivet nuts provide the solution for achieving an internal thread function in a thin or thick metal sheet or profile. Clufix® also allows the assembly of two or more elements in the same way as a rivet, while simultaneously achieving the internal thread function.
Clufix® Blind Rivet Nuts
- Blind Rivet Nuts with Open End
- Applications
- Features

Clufix® open end rivet nuts are used to bring in a strong and reliable thread into a thin or thick metal plates/profile, 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 Clufix® also can be used for onsite repair and maintenance work.

- Blind Rivet Nuts with Closed End
- Applications
- Features

Clufix® closed end rivet nuts are used to bring in a strong and reliable thread into a thin or thick metal plates/profile, 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 IP66 and IP67.
