Rivet Nut Reduced Countersunk Full Hex Closed End

Rivet Nut Reduced Countersunk Full Hex Closed End with a smooth body are a form of internally threaded insert used in applications that require a strong thread to be created in thin sheets of material, for high strength fastening from bolts and other threaded articles. They are commonly used where the material thickness is too small to tap a conventional thread.

The hexagon body of rivet nuts are to be inserted into hexagon drilled holes which prevent the rivet nut from turning or spinning after installation.

The reduced countersunk head allows this type of rivet nut to be used in applications without any extra hole preparation, providing a low profile flush fit to the application. Reduced countersunk rivet nuts can be installed in post-painted or pre-coated applications without damaging the surface.

The closed end style rivet nut is used in applications to reduce corrosion from moisture or contamination, whilst also preventing the use of screws that are too long within the application.

Rivet Nut Reduced Countersunk Full Hex Closed End with a smooth body are installed using a special tool with a threaded stud that engages with the internal threads of the rivet nut and pulls upwards. This deforms the unthreaded section of the rivet nut to expand under the reverse side of the material, providing a high strength permanent thread in thin sheet material.

Available from Fastenright in diameters from M4 to M8 and materials such as Zinc Plated Steel, A2 and A4 Stainless and Aluminium.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
