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.

How Flexco
®
Bolt Hinged
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.
