DOING MORE WITH LESS
STAR FASTENERS
HUCK ® FASTENERS BOOST EFFICIENCY
AND IMPROVE RELIABILITY
Industry is under continued pressure to do
more with less: less weight, less cost, and
less time. Understanding how different
joining technologies function from the
perspective of weight, cost, productivity
and reliability is crucial.
While adhesives are often a popular
joining technology when trying to address
weight concerns, structural blind fasteners
should also be given strong consideration
as they create reliable, effective, tight joints
between various materials.
Structural blind fasteners offer similar
benefits to those of non-structural blind
fasteners, while also providing a distinct
advantage: quantifiable and predictable
shear and tensile strength.
Structural blind fasteners such as
Auto-Bulb™ and PentaLok retain their
mandrel after installation. This retention
of the mandrel is made possible by the
interaction of the mandrel and mandrel
sleeve during the installation process.
The presence of the mandrel accounts for
a 60-80% increase in load-carrying ability
in shear and tensile over conventional
non-structural blind fasteners. Not only
can these fasteners improve joint reliability
due to their added strength, numbers
of fasteners required can be optimised.
In turn, this improves the weight of the
project, speeds-up the manufacturing
process and reduces inventory costs.
THE HUCK AUTO-BULB
This Huck fastener offers the perfect
solution. It works by clamping the joint
with a broad, blind side bulb, which
makes it a good choice for use within
thin materials, and within oversized,
misaligned, or slotted holes. Unlike other
bulbing blind fasteners, Auto-Bulb’s
unique bulbing system creates superior
blind side bearing strength and its
positive mechanical bolt retention ensures
structural integrity. Auto-Bulb is available
in both steel and 400 stainless steel for
corrosion resistance.
Available Sizes: 3/16”, 1/4”
Materials: Steel, 400 Stainless Steel
Headstyles: Protruding, Countersunk

THE HUCK PENTALOK
The Huck PentaLok has been specifically
designed to work with celled, honeycomb,
plastic panels and multi-composite
board. Its wide blind-side footprint is well
suited for use within thin materials and
delicate composites. Pentalok’s uniquely
engineered peel system installs with ease
into shallow panels.
Available Sizes: 1/4”
Materials: Steel
Headstyles: Protruding
Innovative materials and manufacturing
techniques are changing at a rapid pace.
There are numerous reasons why engineers
should use Huck products, such as the ease
by which potential fastening solutions can
be calculated and dimensioned, as well as
the consistent quality of products.
Selecting an appropriate fastener can be
challenging. Star Fasteners work closely
with engineers and procurement teams to
share their specialist fastener knowledge.
A smart customer focused response, as
well as large stocks ensures that customers’
requirements are met quickly.
