How to Specify the
Correct Flexco
®
Bolt Solid
Plate 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, steel
is recommended.
MegAlloy
®
.
For superior resistance to wear
and abrasion.
Stainless Steel.
Type 316 Stainless Steel
provides extra resistance to abrasion,
magnetic attraction and corrosion from
acids and chemicals.
Everdur
®
.
Spark-free material compared to
steel and fully non-magnetic.
Flexco
®
VP
™
.
Rubber covered steel
top plates.
Promal.
For superior abrasion resistance. Some
minor chemical and corrosion resistance.
No Hinge Pin Required.

How Flexco
®
Bolt Solid Plate
Fasteners Work
Strength of this fastener is derived from the
compression of the plates, mounted above and
below the belt, with high tensile strength bolts.
This "compression" distributes the splice tension
across the full width of each fastener plate.
The holding ability is, thereby, increased by not
solely relying upon the bolts to resist pull-out.
Additional strength and resistance to pull-out
is obtained from the specially formed teeth on
each plate. These teeth imbed deep into the belt
carcass, without damaging the carcass fibers.
A tight butt splice is achieved through the
exaggerated bolt hole spacing in the templet
which forces the belt end together. Flexco
®
Bolt Solid Plate Fasteners permit natural
conformance with troughing or transition idlers.
140, 190
and 2-1/2 size fasteners are specifically
designed for thinner belting, allowing increased
compression, greater reach-back, and more
fastener plates per belt width.
