See the LockBolt in action
The
classic 6-groove locking fastener built with staying power.
A result of Huck International innovation a half-century ago,
the versatile Alcoa Fastening Systems C6L® Lock Bolt remains the
number one fastening system for applications that require a
strong, vibration-resistant seal today.
C6L’s exclusive locking groove design ensures a permanent fit
that resists loosening. That means it’s ideal for applications
from general
manufacturing to such high-vibration applications as HVAC,
trailer and container assembly, rotary and rotating equipment,
shopping carts, railroad and transit cars, geodesic structures,
and many others.
In addition to offering superior fastening performance, the C6L
system reduces labor and installation costs, along with rework
and warranty expenses. For example, using the C6L eliminates the
need to hire certified welders or specially trained employees,
because workers can be instructed to install these foolproof
fasteners in a matter of minutes. The C6L is simply stronger,
easier to install, and more durable than welding, adhesives, or
conventional threaded fastening systems.
Designed for consistent installation, easy inspection.
The C6L’s unique design virtually eliminates installation errors
caused by operator or tool variables. The C6L ensures that once
the collar swage is complete, the pintail breaks off and the
fastener is tightly installed. No rework required. And you can
count on consistent, high-uniform clamp force with every C6L
installation, time after time.
A quick visual inspection, along with an occasional dimensional
check, is all that’s required to make sure the C6L is installed
accurately.
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 fasteningn
company can match this level of premium, value-added support.
