Plastic Rivet Fastener Selection Chart
Alligator
®
Non-Metallic Fasteners are made
up of two distinct product lines, the Alligator
®
Plastic Rivet System and the Alligator
®
Spiral
Lace Fastener System.
The
Alligator
®
Plastic Rivet Fasteners
were
developed to bring the many advantages of
mechanical belt fasteners to those applications
where metal belt fasteners could not be used.
They are external, cover-mounted fasteners
employing a one-piece, integrated design with
rivets molded into the top plates of the fasteners.
These rivets pass through pre-punched holes
and are formed over through our Spin-Set
TM
technology, compressing the fastener plates and
finishing the splice.
The
Alligator
®
Spiral Lace Fastener
system
was designed for small pulley, low-profile
applications. The fastener is constructed of
polyester webbing, spirals, and hinge pins. It is
installed by either insertion between the plies,
ply stepping, or finger splicing.

1. Determine Belt Tension (PIW).
2. Measure your Belt Thickness.
3. Measure the Diameter of the
Smallest Pulley in your Drive
with Belt Wrap more than 90°.
4. Choose the fastener size
that is appropriate for your
specifications in the selection
