Why Lockbolt Fasteners?
- Low installed cost
- Vibration and fatigue resistant
- Consistent installation
- Reduced rework and warranty costs
Avdel Cherry lockbolts are designed to meet the higher life
cycle demands of today's new equipment designs. Lockbolts offer
time savings during assembly and long-term savings in reduced
warranty claims. The advantages offered by lockbolts are:
- Low Installed Cost The ease of assembly and speed
at which the lockbolts can be installed will reduce the
final in-place costs.
- Vibration and Fatigue Resistant As permanent as a
weld, a lockbolt resists loosening when all other methods
fail.
- Consistent Installation Lockbolts are designed to
eliminate installation errors caused by operators or
tools.
- Reduced Rework and Warranty Costs Lockbolts are
designed to install properly every time and to stay tight
in the application.

Installation
The installation of Avdel Cherry lockbolts is
fast and precise with the use of our hydra-pneumatic tooling.
- The lockbolt is inserted into the prepared hole.
- The collar is placed on the lockbolt.
- The tool pulls on the tail of the bolt, drawing
the sheets together and forming the collar into
the locking grooves.
- After the collar is completely formed onto the
bolt, the tool continues to pull until the tail
of the bolt is tensioned off.

Selecting The Proper Lockbolt
- Select a lockbolt that meets shear, tensile and
head style requirements.
- Select a material that is compatible with the
materials being joined and the environment the
application will be
subjected to.
- Measure the combined thickness of all materials
to be joined. You must add to the grip when using
a flanged
collar. Refer to drawings for actual dimensions.
