Pierce and fasten in one operation without sacrificing joint quality. With Fastriv, piercing and joining take place at one time, so pre-drilled holes, hole preparation, and hole alignment are eliminated resulting in higher productivity and more cost-effective assembly.

Fastriv is an excellent fastener for joining dissimilar materials, pre-coated sheets, or layered materials. This makes it an efficient fastening solution over methods such as spot welding, bolting, adhesive bonding, clinching, or blind riveting.

Unlike welding, Fastriv self-piercing rivets do not create a heat zone in the materials during installation, so damage to application materials are minimized. Additionally, unlike other methods, the installation process is clean, quiet, and operator friendly.

A wide variety of installation tooling – from hand-operated systems to automated assembly lines - is available to place Fastriv fasteners. Each can be customized to meet the specific requirements of your assembly line and decrease your installed costs.

Fastriv systems provide a very efficient working process, reducing assembly times to a minimum. They are especially cost-effective for medium- and large-volume production.

Fast Facts:

  • Join dissimilar materials, pre-coated sheets, or layered materials.
  • Pierce and fasten in one operation, eliminating need for insertion holes and alignment.
  • No heat affected zone created in assembly process.
  • Provides consistent, high joint strength, comparable to spot welds and other mechanical fastening methods.
  • Clean assembly process generating no fumes, sparks, or swarf.
  • Self-sealing rivet radially expands into material, without breaking through substrate.
  • Process load monitoring can be incorporated into installation tooling system to track and notify operator of variances in joint.
  • Installation systems are adapted to specific production processes – from hand-operated systems to automated assembly lines.
  • Available as a customized design to meet your unique assembly requirements.
  • Assembly applications include automotive space frames, automotive subassemblies, car seats, instrument panels, air cargo equipment, domestic appliances, construction components, and ladders.
