Reduced countersunk (thin sheet) full hexagon rivet nuts with a smooth body and closed end are also commonly know as Rivnuts, Blind Nuts, Thin Sheet Nuts and Nutserts.
These rivet nut fasteners are a form of internally threaded insert and are used in applications where the material (wall) thickness is too small to tap a conventional thread, therefore by using rivet nuts a strong thread is created in thin sheets of material for high strength fastening from bolts and other threaded articles.
The closed end style rivet nut is used in applications to reduce corrosion from moisture or contamination, the closed end rivet nut also prevents screws that are too long been used in the application.
The reduced countersunk head also known as thin sheet rivet nuts allows this type of rivet nut to be used in applications without any extra hole preperation, providing a low profile flush fit to the application. Enabling reduced countersunk rivet nuts to be installed in post-painted or pre-coated applications without damaging the surface.
The hexagon body rivet nuts are to be inserted into hexagon drilled holes which prevent the rivet nut from turning / spinning after instillation.
Reduced countersunk (thin sheet) hexagon rivet nuts with a smooth body and closed end are installed using a special tool with a threaded stud (nose) that engages with the internal threads of the rivet nut an pulls upwards, in turn deforming the unthreaded section of the rivet nut to expand under the reverse side side of the material, providing a high strength permanent thread in a thin sheet material.
