Avdel Breakstem Rivets : Avibulb®


AVIBULB® Fastening System

All-steel bulbing breakstem rivet. Excellent clamp-up and superior shear and tensile strength result in a vibration resistant joint. Smooth bulb formation is ideal for thin backside material.

Benefits:

  • All-Steel Construction
    Provides extremely high shear and tensile strengths.
  • Bulbing Tail Formation
    Large bearing surface is ideal when thin backside material is part of the assembly. Pull-out is increased and thin material is not deformed.
  • Positively Locked Stem
    High clamp-up and positive stem retention ensures a vibration resistant joint.

  • Low Profile Head
  • Shear & Tensile Strength
  • Material and Finish
