Flexco® Bolt Solid Plate Fastening System

  • Bolt Solid App
  • Bolt Solid Glam
  • Bolt Solid Installation

The Flexco® Bolt Solid Plate Fastening System produces a strong, sift-free splice with superior holding ability thanks to a combination of top-and-bottom plate compression and high-tensile-strength bolts. 

Why Bolt Solid Plate?

  • Mechanical fastener rating from 150 to 620 PIW (300 to 1080 kN/m)
  • Belts from 3/16” to 2” (5 mm to 50 mm) thick
  • Pulley diameters from 12” to 48” (300 mm to 1220 mm)
  • Sift-free splice perfect for sand, gravel, crushed stone, and cement
  • Specially formed teeth penetrate belt carcass without damaging fibers
  • Piloted bolts for quick and easy installation
  • Available with rubber-covered top plates for increased impact protection and compatibility with conveyor components

Installation Method

  • Portable tooling
  • Choice of hand or power installation
  • Fasteners

How Flexco® Bolt Solid Plate Fasteners Work Rivet Hinged SR 

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.

FASTENER METALS AND AVAILABILITY

To maximize fastener service life, fastener material must be matched to the application. Flexco manufactures fasteners from a broad range of materials. Our selection makes it easy to specify a fastener that will deliver maximum performance in a variety of conditions—from wet and abrasive applications to highly corrosive environments.

Steel: Standard fastener metal that is not recommended for environments where corrosion can occur from acids and chemicals. Galvanized Steel: For basic applications, galvanized steel is recommended. It is magnetic, offers good abrasion and rust resistance, but is not
recommended for corrosive environments.
Stainless Steel: Stainless steel provides extra resistance to abrasion, magnetic attraction, and corrosion from acids and other chemicals.
MegAlloy®: Features superior resistance to wear and abrasion. Provides several times the service life of steel. Not recommended where
impact of corrosion is a problem.
Everdur: A corrosion-resistant copper and silicon alloy. Fully non-magnetic and spark-free, low in resistance to abrasion.
Rubber-Covered Steel Top Plates: Our bolt solid plate fasteners are available with rubber-covered top plates, either as individual plates or as a 6-plate Flexco® VP™ strip, for excellent resistance to abrasion. Bottom plates are manufactured from steel or MegAlloy®.
