blind rivet nut / steel
The Rivet Nut is designed with four holes to control the deformation of the body. This property enables the use of Rivet Nuts in applications and materials where they would otherwise not be suitable.
Rivet Nuts include four holes in the deformable shank or body of the Rivet Nut. As the Rivet Nut is installed the location of the holes determines where the bulge will start and how it develops.
This feature enables the use of Rivet Nuts where standard Rivet Nuts would not be suitable. Such as in Plastics, Composites, Wood, and where it is necessary to install into oversize or irregularly shaped holes.
The controlled bulge has a number of distinct benefits:
Reduced stress in the parent material.
Larger deformed diameter for a given size.
Wide grip range.
High pull through strength.
Use in soft materials.
