What are Countersunk Rivet Nuts?

Countersunk Rivet Nuts (also called blind Rivnuts) are substantially similar to a regular rivet nut, except that the head is COUNTERSUNK to seat flush after being installed into the surface of the parent material! They are commonly used in applications where a smooth, flush finish is required, such as in automotive (think, “mounting the dashboard for a sleek appearance”) or aerospace applications (think, “smooth surfaces of an airplane for best aerodynamics”). Countersunk rivet nuts are installed the same way a regular rivet nut is. However, the hole the countersunk rivet nut is dropped into must also be countersunk, or it will not sit flush with the surface. Countersunk rivet nuts require the parent material to be slightly thicker than a regular rivet nut because the rivet nut hole must be drilled a countersunk hole, which removes more of the parent material when countersinking the hole. A unified threaded countersunk head usually has a 100° angle, while a metric threaded countersunk usually has a 90° angle.

Countersunk Metric Rivet Application Notes:

The type of sheet material being used can affect the grip range of these revenues. It is recommended that a few test installations be conducted to determine the appropriate grip range for your specific application.

The countersunk head European-style rivnut is installed using hand tools that can be pneumatic, hydraulic, or manual. The installation process is simple, easily controlled, and less labor-intensive than other processes associated with nuts and bolts. When properly inserted, the nutsert head will be flush with the surrounding sheet material.

The closed-end version of these revenues will effectively seal the back end of the nut and provide a barrier against external contaminants.

These nutserts are easy to use and highly versatile. They will effectively reduce or eliminate the use of nuts and bolts within your application and could significantly reduce assembly times and labor costs.
