How to Specify
the Correct Flexco ®
Bolt Hinged Fastener
Fastener Metal
Selection Hinge Pin Selection
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 chart below.
Steel. For most applications, plated
steel is recommended.
Stainless Steel. Type 316 Stainless
Steel provides extra resistance
to abrasion, magnetic
attraction, and corrosion from
acids and chemicals.
MegAlloy ®. For superior resistance
to wear and abrasion.
Everdur® . Spark-free material
compared to steel and fully
non-magnetic.
NC Nylon Covered Steel Cable -
for use with steel fasteners, flat
or troughed belts.
NCS Nylon Covered Stainless Steel Cable -
for applications with stainless fasteners,
flat or troughed belts.
NAC Nylon Covered Armored Cable - right
for many applications, long service life.
AC Bare Armored Cable - for extendable
conveyors.
ACS Bare Armored Stainless Cable - for
applications with stainless fasteners,
flat or troughed belts.
SC Bare Steel Cable - for conveying gritty
or abrasive material.
SSC Bare Stainless Steel Cable -
for corrosion resistance, flat belts.
NB Nylon Covered Bronze Cable -
for non-magnetic joints.

Fasteners Work
Flexco® Bolt Hinged fasteners
provide a flexible joint for belts
operating over small pulleys.
Because the joint is easily
separated by simply removing the hinge pin, entire belt
sections may be added or eliminated.
Designed as a compression fastener, the Flexco® Bolt
Hinged model is fastened to the belt ends with high
strength bolts. The bolts compress the plates into the belt
cover. Additional holding capability is provided by the
fastener teeth that imbed in the belt without damage to the
belt carcass.
This combination distributes the splice tension across the
entire plate width while the teeth secure the fastener into
the belt carcass to resist pull-out.
