Why Breakstem Rivets?
- Low installed cost
- Blind installation
- Permanent, reliable fastening
- Lightweight, ergonomic tooling
Avdel Cherry blind 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 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 are installed will reduce the final
in-place cost of the product manufactured.
- Blind Installation: The ability
to place Avdel Cherry breakstem rivets from only one side of the workpiece
increases the speed and efficiency of the assembly.
- Permanent, Reliable Fastening:
Blind rivets securely assemble applications and provide a vibration
resistant joint. They will not work loose like threaded fasteners.
- Lightweight Ergonomic Tooling: Avdel
Cherry tooling has been designed with the operator in mind. Torque reliant
tooling may cause Carpal Tunnel Syndrome or other repetitive motion
injuries.
Installation
The installation of Avdel Cherry blind rivets is
easily accomplished with the use of either hand or power riveters. 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 rivet.
NOTE: Good design practice dictates that a
fastener should not be used in applications which fall outside of the specified
grip range or recommended holesize.
