Large flange, full hexagonal body rivet nuts combine two key features for enhanced strength and stability:

  1. Large Flange Head – Provides a wider load-bearing surface, distributing force more evenly across the parent material. This helps prevent pull-through and enhances support in softer or thinner materials like aluminum or composites.
  2. Full Hexagonal Body – Offers maximum resistance to spinning, especially in high-vibration applications. When installed in a hex-shaped hole, this design ensures a secure grip, preventing the rivet nut from rotating under torque.


Rivnuts (also known as nutserts, blind nuts, or threaded inserts) are a fast, reliable, and cost-effective way to create strong, load-bearing threads to thin or brittle materials—especially when access to the back is limited.  They are installed into a parent material, allowing a secondary component to be securely bolted in place.

Designed as a variation of a standard rivet, rivnuts feature a tubular body (round, knurled or hexagonal) with internal threading. They can be installed in sheet materials as thin as 0.50mm and offer one-sided (blind) installation, making them a versatile solution for many applications.
