• Foundries
Holes are punched in belt quickly and
accurately with a templet and boring
tool. Fasteners are installed on-site with
portable, hand, or power tools.

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 specifcations
in the selection chart below.
Steel.
For most applications, plated
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.

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 fbers.
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 specifcally designed
for thinner belting, allowing increased compression, greater
reach-back, and more fastener plates per belt width.
