Why Structural Breakstem
Fasteners?
- Low installed cost
- Blind installation
- Permanent, reliable fastening
- Lightweight, ergonomic tooling
Avdel Cherry structural breakstem rivets have been designed to
fulfill a variety of functions across a wide range of assembly
applications. Labor-intensive operations which require access to
both sides are made obsolete with Avdel Cherry's structural
breakstem rivet range. The advantages offered by these unique
fastening methods are:
- Low Installed Cost: The ease of assembly and speed
at which the rivets.
- Blind Installation: The ability to place Avdel
Cherry structural breakstem rivets from only one side of
the workpiece increases the speed and efficiency of the
assembly.
- Permanent, Reliable Fastening: Structural
Breakstem fasteners provide secure assembly and provide a
vibration-resistant joint.
- Lightweight Ergonomic Tooling: Avdel Cherry
tooling has been designed with the operator in mind.
Structural breakstem fasteners are installed with tension
placing tools Torque-reliant tooling may cause Carpel
Tunnnel Syndrome or other repetitive motion injuries.

Installation
The installation of Avdel Cherry structural
blind rivets is easily accomplished with the use of
hydra-pneumatic tools. Avdel Cherry manufactures tools from basic
handheld tooling to elaborate multihead and/or bowl-fed
equipment.
- The rivet is inserted into the prepared hole.
- As the stem is pulled by a rivet tool, the blind portion
of the rivet expands radially and pulls the application
material firmly together.
- When the rivet is fully expanded, the stem breaks and the
installation process is complete.

Selecting the Proper Fastener
- Select a rivet group that meets the shear and tensile
requirements for the application.
- Select a rivet material that is compatible with the
materials being joined. As a general rule the rivet
material should have the same physical and mechanical
properties as those being joined. Using a dissimilar
material may cause joint failure due to either material
fatigue or galvanic corrosion.
- Determine the type of head style required based upon the
application material and hole preparation.
- Measure the thickness of the material to be joined (grip)
and prepare the hole for the proper diameter of the
rivet.
NOTE:
Good design practice dictates that a
fastener should not be used in material thicknesses which fall
outside of the specified grip range or recommended hole size.
