Oops, an error occurred! Code: 20211017170939169117fb


The Avdel Briv® Speed Fastening® System have a bulbed tail providing consistent high clamp and shear, making it ideal for assembling many materials including metal, plastic and aluminum alloy. With easy installation and lower in-place costs than welding or nail rivet, this speed riveting system is extensively used for light fabrication needs.  

Key features and benefits

  • Bulbed tail and foreshortening of the fastener during installation ensures high clamp
  • Bulbed tail and large headform provide a large bearing area for soft materials
  • Tapered tail for ease of hole entry
  • Expands radially during installation to ensure maximum hole fill
  • Lower in-place costs than welding or nail rivets
  • Hot tin dipped brass option for ease of soldering and good electrical continuity
  • Stainless Steel option for applications subject to high temperatures or corrosion
  • Placed using a unique repetition mandrel system for high speed assembly
  • Can be bowl fed for larger volume applications using automated equipment
