C50L HuckBolt
®
®
Grade 5 fasteners certified to meet or exceed all ASTM A-325 standards.
For applications ranging from railcar to mining equipment
manufacturing, C50L® HuckBolt® fasteners from Alcoa
Fastening Systems offer superior vibration resistance and
overall durability. Heavy-duty applications demand tough,
reliable fasteners. And extensive testing has demonstrated that
C50L HuckBolt fasteners meet or exceed the performance
of torqued bolts in both shear and tensile strength (with a
longer fatigue life). Value is built in, too. Over the lifetime of
your product, the investment you make in the quality of C50L
HuckBolt fasteners will pay for itself. You won’t find a stronger,
more reliable fastening system, no matter what your application.
2
Installs safer and quieter
The C50L HuckBolt system is engineered to be installed without torquing or multiple impacts. Noise level is significantly
reduced, and as a result, your installation area becomes quieter, less stressful, and more productive.
1
The pin is inserted into the prepared
hole and the smooth bore collar is
placed on the pin
2
3
The installation tool is applied to the
pintail. When the tool is activated, the
jaws in the nose assembly pull on the
pintail and the nose anvil pushes on
the collar to remove any gap.
The nose anvil starts to swage the
collar into the lockgrooves on the pin.
Continued swaging causes the collar
to lengthen and develop clamp.
4
When swaging of the collar into
the lockgrooves is complete, the
pintail separates from the pin which
completes the installation cycle.
Successful, consistent installations
Unlike threaded fasteners, the C50L HuckBolt delivers consistent
installation results. High costs of calibrating, maintaining, and
replacing tools are eliminated. And installation does not require
expensive, highly experienced workers.
Swaged-on collar forms a permanent,
vibration-proof connection
■
Initial long length of fastener
enables pull-out of large gaps
■
Pre-load remains consistant from
installation-to-installation

1 When using 3LC collars, include J dimension in grip dimension to determine grip number.
2 Optional collar at reduced clamping force and tensile strength. Contact AFS for data. When using 8LC collars,
subtract J dimension from grip dimension to determine grip number.
3 H length for 20 (5/8") diameter in F, I or 2CU material is 805 - 770.
