Rivet Nut Reduced Countersunk Half Hex Open End

Rivet Nut Reduced Countersunk Half Hex Open End are installed using a special tool with a threaded stud that engages with the internal threads of the rivet nut and pulls upwards – which 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.

The half hexagon body rivet nuts make locating within a predrilled hole easier, reducing the speed of the installation process. They are 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. This enables countersunk rivet nuts to be installed in post-painted or pre-coated applications without damaging the surface.

With an open end style rivet nut allows the stud or male threaded component to thread through the nut without limiting the length or protrusion of the male threaded part.

Rivet Nut Reduced Countersunk Half Hex Open End are a form of internally threaded insert and are used in applications where the material thickness is too small to tap a conventional thread.

Available at Fastenright in thread sizes M3 to M12. Manufactured from Zinc-Plated Steel, A2 Stainless Steel and A4 Stainless Steel as standard.

Non-standard sizes and materials are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
