Product Brochure

The unique design of Magna-Bulb® ensures a tight fit,
no matter what the application.
T
he Magna-Bulb® blind fastening
system from Alcoa was designed to
ensure a strong hold and tight joints
within a wide variety of materials,
including plastic, fiberglass, metal,
and composite fabrication.
The wide, blind footprint design is
the key. Magna-Bulb was engineered
specifically for blind side sheets,
featuring a broader bearing surface
which helps to spread the load over
more area. Ultimately, this creates a
stronger, longer-lasting connection.
What’s more, an internal
mechanical solid-circle lock design
adds pin retention strength. And the
wide bulb on the blind side
eliminates pull-through with thin
materials. So even on low-strength
materials, Magna-Bulb creates a
full-strength joint.
Environment and budget
friendly installation.
Because Magna-Bulb fasteners
aren’t installed with torque wrenches, welding equipment, or riveters’
hammers, they offer an inherently
quieter work environment.
And since workers experience
fewer injuries and less fatigue using
our revolutionary tooling system,
you’ll experience added cost savings.
Easy, one-step operation
and inspection.
The Magna-Bulb system
eliminates the need to hire certified
welders or specially trained
employees, because workers can be
instructed to install these foolproof
fasteners in 10 minutes. Installations
are more accurate than other
fasteners of the same kind, because
the element of human error is not an
issue. In other words, correct
installation doesn’t depend on
operator skill or specialized tools. If
the core pin is flush, then the
installation is successful; a quick visual
inspection is all you need. Torque
inspections or x-rays aren’t necessary.
And the lock is repeatable –there’s
no need to grind or fill.
Strong support.
Alcoa Fastening Systems’ skilled
and knowledgeable technicians
– your Huck System Specialists – are
ready and waiting with valuable
consultation, evaluation, installation
assistance, and in-depth staff training capabilities. No other fastening
company can match this level of premium, value-added support.

The pin is inserted into the
prepared hole while the collar is
threaded onto the pin by hand.

the collar, pressing or swaging the collar material into the
threads of the fastener for a
secure, permanent joint.
4
The pintail breaks off and the
tool spins off, completing the
installation in about half the
time required for an ordinary
torqued fastener.

The Benefits of Huck Fastening Systems
Huck fastening systems deliver a number of important benefits, making them the worldwide leader.
• Easy to use – consistent accuracy with little operator
training required
• High productivity – reducing installation time by 25% to 50%
• Reduced QC procedures – a visual inspection is sufficient to verify
a correct installation
• Consistant high-clamp performance – typically much higher than
with conventional fasteners
• Durability – extremely high clamp force retention, with 10%
to 20% greater fatigue life than conventional threaded fasteners
