Blind Threaded Inserts

Deform-Nut® & Rivet Nuts

High-Strength, Blind-Side Threading for Thin Materials

The Deform-Nut® by Specialinsert is an innovative metal tubular threaded rivet that provides strong, reusable, load-bearing threads in sheet metal, plastics, tubes, and composite materials.

Commonly known in the industry as rivet nuts or Riv-Nuts, these inserts are the ideal solution when material is too thin to be tapped (minimum thickness of 0.5 mm) or when you have no access to the inside of the workpiece.

Why Use Deform-Nut®?

• Blind Installation: Install easily from one side of the workpiece.
• No Welding Needed: A valid alternative to the use of welded nuts, eliminating weld spatter and refinishing.
• High Pull-Out Strength: High mechanical sealing characteristics and resistance to torque.
• Versatile Materials: Fits aluminum, steel, fibreglass, plastic and composite materials.

Common Applications

• Automotive & Transportation assembly
• Sheet metal, tubular, and box structures
• Marine & Aerospace interiors
• Electrical enclosures & control panels
