Rivscrew®

Threaded, removable speed fasteners that combine the speed of rivet placement with the benefits of being able to remove and re-fasten.

Overview

The Avdel Rivscrew® Speed Fastening® system is a threaded, removable speed fastener that combines the speed of rivet placement with the benefits of being able to remove and re-fasten. Using a Rivscrew rivet removes the need for costly tapping or thread forming operation whilst creating a higher vibration resistant ‘thread lock’ compared to standard screws.

Please explore our Rivscrew® e-Brochure:

Key features and benefits

  • Expands radially during installation to form a thread in host material
  • Removable for servicing with a hex key and reusable
  • Various lengths available providing high clamp loads
  • Placed using a hexagon mandrel which expands the threaded diameter radially, adjacent to its six corners.
  • Providing a higher vibration resistant "thread lock" in the parent material compared to standard screws
  • Can be used to fasten most materials up to Vickers hardness 105 Hv5
  • Eliminates the need for costly tapping or thread-forming operations
  • Brigth tin plated steel option for ease of soldering and increase electrical conductivity
  • Placed using a unique repetition mandrel system for high speed assembly
  • Can be bowl fed for larger volume applications using automated equipment
