When you need strong and you need fast – you need NeoSpeed®. NeoSpeed® is the strongest, most versatile Speed Fastening system on the market. The Avdel® NeoSpeed® fastening process delivers a throughput up to four times greater than traditional threaded or breakstem fasteners.

Designed and optimized using class-leading finite element analysis techniques, NeoSpeed® has a unique splined rivet design that is an industry exclusive. These speed fasteners combine high clamp throughout a wide grip range. NeoSpeed® also offers multi-grip capability to accommodate wide variations in material thickness.

NeoSpeed® lets you do more with less. It is also about half the installed weight of an equivalent breakstem rivet, and one NeoSpeed® rivet can be used to replace several standard grip fasteners.

Most NeoSpeed® variations can be supplied as either a paper magazine of fasteners, or a pre-loaded disposable mandrel "cartridge.”

Fast Facts:

  • Multi-grip capability accommodates wide variations in material thickness.
  • One rivet can be used to replace several standard grip fasteners.
  • External splines fill rear sheet and oversize front sheet holes.
  • 3x greater hole-size tolerance than standard breakstem rivets.
  • Far less sensitive to application variations.
  • Easier specification due to one-rivet x one-mandrel solution.
  • Typically half the installed weight versus an equivalent breakstem rivet.
  • Either magazine-fed or fed via a vibrating bowl to a wide choice of installation equipment.
  • Assembly applications where you will find NeoSpeed® fasteners include automotive, electronic, domestic appliance, electrical equipment, and general light fabrication.
