BOLT SOLID PLATE FASTENERS

Bolt Solid Plate Fasteners

Bolt Solid Plate Fastener System

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, but without damaging the carcass fibers.
 
A tight butt splice is achieved through the exaggerated bolt hole spacing in the templet which forces the belt ends together. And, the Bolt Solid Plate Fasteners permit natural conformance with troughing or transition idlers.
 
The 140, 190 and 2¼ size fasteners are specifically designed for today's thinner belting, allowing increased compression, greater reach-back and more fastener plates per belt width.

Fastener Metals

Options

Bolt Solid Plate fasteners come in a variety of metals for many applications.

Steel

For most applications, the standard fastener material, carbon steel, is suitable. Available in all sizes.

Stainless Steel

Type 316 is non-rusting and provides extra resistance to abrasion, magnetic attraction and corrosion from acids and chemicals. Available in all sizes except No. 2½ and 3. Furnished as Stainless Top Plates with the balance steel or as all stainless, including bolts and nuts.

Everdur

Spark-free material compared to steel and fully non-magnetic. Alloy of copper and silicon for use in grain elevators and other potentially explosive environments, or on belts with magnetic pulleys or separators. The word Everdur is a trademark of American Brass.

Megalloy

For superior resistance to wear and abrasion, Megalloy is available in sizes 140, 190, 1½, 2, 2¼ and SP6. Provides several times the service life of regular steel. Not recommended where corrosion is a problem. Megalloy is a trademark of Flexible Steel Lacing Company.

Monel

Where abrasion, rust or corrosive acids quickly deteriorate steel, this nickel/copper alloy is effective. It is available in sizes 1, 1½, 2, 2½ and 3 only, and furnished as Monel Top Plates, balance steel or all Monel, including bolts and nuts. The word Monel is a trademark of Huntington Alloys, Inc.

Promal

For severe abrasion resistance in corrosive environments such as coke and sinter operations, use Promal Top Plates. These are heat treated, malleable castings. Promal Top Plates (available in Nos. 140, 190 and 1½) furnished with steel bolts, nuts and bottom plates. The word Promal is a trademark of FMC Corporation.

Rubber-Covered Steel

To maintain a smooth surface when splice has been countersunk with the JV tool and router method, use Rubber-Covered Top Plates. They fill the space above the top plate with a 1/8" thick rubber cover for a continuous, smooth belt surface.

Bolt Solid Plate Installation Tools and Supplies

The only tools needed for installing Solid Plate fasteners are a templet and simple, portable hand tools. Impact wrench driven power tools are suggested since they can speed installation time by as much as 50%.

Templets

Templets insure precise hole placement for a tight splice. Templets install one size fastener only. Templets are not interchangeable among fastener sizes, but certain templet widths of a given size may be interchanged in an emergency.

Note: A 45º splice requires a special templet. Please call for information.

Hand or Power Tools for Bolt Solid Plate Fasteners

In addition to a templet, the following hand or power tools are required for installation: a punch or a boring bit (the punch is preferred for general use and where the belt cover is over 3/16" thick); a wrench; and two bolt breakers.
 
A power impact wrench cuts application time by approximately 50%. It should be used with a "quick change chuck" which adapts the tools to the square drive stud on an air or electric impact wrench.
