Thin Sheet Nutsert®

Inserts designed to provide load bearing threads in thin sheet materials.

The Avdel Thin Sheet Nutsert is a blind threaded insert designed to provide load bearing threads in thin sheet materials. The large flange version gives the Thin Sheet Nutsert rivet nut a greater load bearing surface whilst a closed end prevents the ingress of dirt and fluids into the thread and electrical circuits.

Key features and benefits

  • Can be used in very thin sheet materials from 0.50mm (0.02")
  • Access needed from only one side of the application, for high speed assembly
  • Provides a female thread in application
  • Can be installed in pre-coated or post painted applications without damaging the surface
  • Various platings available to increase the corrosion resistance
  • Low profile head allows near flush fit to application and clamps two or more sheets of material together, within the grip range
  • Large flange head provides a load bearing surface and reinforces the hole to prevent push-out. Can be used as a spacer and can be supplied with an under-head seal
  • Closed end prevents the ingress of dirt and fluids into thread and electrical circuits
  • Can be used with hand tools, pneumatic tools and fully automated machines to suit a wide range of assembly methods
