Grip range refers to the material thickness the rivet nut can clamp. Thread size identifies the mating screw or bolt, rather than the installation hole diameter. Metric values are conversions of the listed imperial dimensions.
Typical Applications
- Vehicle panels and bodywork.
- Sheet metal fabrication and enclosures.
- Repairs requiring an imperial threaded attachment point.
Selection and Installation
Select a rivet nut whose grip range covers the material thickness. Prepare the correct fitting hole and install using a suitable rivet nut tool with the matching UNC mandrel. Check the setting on a sample before completing the assembly.
Pack Sizes
Available individually or in packs of 5, 10, 20, 50 or 100. Select the required thread size and quantity from the options above.
