Rivet Nut Corrosion Resistant Flange Head Half Hex Body

Rivet Nut Corrosion Resistant Flange Head Half Hex Body fasteners can fit into a hexagon hole, eliminating the issue for potential turning post-installation. They are often referred to as Rivnuts, Blind Nuts, Thin Sheet Nuts and Nutserts.

These rivet nuts 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. Using rivet nuts creates a strong thread in thin sheets of material for high strength fastening from bolts and other threaded articles.

The A4 grade Stainless Steel is the most corrosion resistant grade used for fasteners – holding increased percentages of Nickel and Molybdenum – meaning a better resistance against aggressive conditions, acids, chlorides and coastal or marine applications.

Rivet Nut Corrosion Resistant Flange Head Half Hex Body fasteners are installed using a special tool with a threaded stud (nose) that engages with the internal threads of the rivet nut and pulls upwards, in turn deforming the unthreaded section of the rivet nut to expand under the reverse side of the material. This provides a high strength permanent thread in thin sheet material.

Manufactured in A4 Stainless Steel as standard, available in sizes from M4 to M10.

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