VERBUS-RIPP® is a new development in the field of mechanical self-locking fasteners.

 Alternative self-locking systems use a saw-tooth principle; teeth are set at an angle against the direction of unscrewing, during tightening these teeth cut into the parent material in order to anchor the fastener.

 The VERBUS-RIPP® self-locking system features locking ribs which do not cut into the parent material. Instead of cutting, the special shaped VERBUS-RIPP® ribs use a cold forming principle to lock into the contact surface. This achieves a far more effective self-locking effect, without causing damage to the contact surface.

  • The locking ribs cover the entire contact surface
  • During the tightening process the mating material is "burnished/sleeked"
  • Plastic deformation with compacting the surface
  • The locking ribs limit the yield of connection, guaranteeing minimum creep and outstanding reusability

Features

  • VERBUS-RIPP® underhead ribs
  • Surface friendly locking system
  • All purpose
  • Easy to tighten
  • Ideal for applications under vibration loading

Benefits

  • Reduces the loss of clamping force
  • Can eliminate need for additional washers, reducing cost and complexity
  • No damage to the contact surface during removal due to unique underhead geometry
  • All VERBUS-RIPP® variants are reusable
  • Ideal for soft materials, joining thin sheet metals and heat treated surfaces
  • Does not cut into the surface
  • Meets all customer requirements

Specifications

VERBUS-RIPP® screws are made as case-hardened -class 100-(case hardness 400-550 HV1) screws with a minimum tensile strength of 1040 -(1200) N/mm²and in a fully quenched and subsequently tempered version with strength class 12.9 according to DIN EN 20898-1.
