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 2 ¼ 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

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

Hinged bolt 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 bolt hinged model is fastened to the belt ends with high strength bolts. These compress the plates into the belt cover. Additional holding capabilities 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.

375X

Designed for belt conveyors with center distances less than 1000 feet.

For belts 1/4″ to 13/32″ thick.

Use on belts with mechanical fastener ratings up to 190 PIW.

Operates over 6″ minimum pulley diameter.

Fastener strips ensure a straight splice and faster installation.

Available in complete joints for various belt widths or in bulk fasteners without hinge pins.

550

For belts 1/4″ to 5/8″ thick.

Use on belts with mechanical fastener ratings up to 300 PIW.

Ordering Numbers

Each “J” carton contains one complete belt joint. This includes: fasteners, hinge pin, filler tubing, bolts and nuts; assembly clips and a gauge rod for easy installation. (The connected fastener strips, 375X and certain widths of 550 strip, do not require clips, so none are included.)

Hinge Pins for Bolt Hinged Lacing

SC - Bare Steel Cable

For conveying gritty or highly abrasive material, Bare Steel Cable (SC) is recommended. Offered for numbers 375X and 550 fasteners only.

NCS - Nylon Covered Stainless Steel Cable

For greater corrosion resistance, the Nylon Covered Stainless Steel Cable (NCS) is furnished standard with Stainless joints. In is notrecommended for use with deep troughing idlers over 35 º.

NC - Nylon Covered Steel Cable

The nylon coating reduces corrosion and makes pin insertion easier.

NB - Nylon Covered Bronze Cable

For a non-magnetic joint, use fully non-magnetic Nylon Covered Bronze Cable (NB) with Everdur fasteners.

SSC - Bare Stainless Steel Cable

Where corrosion attacks steel cable hinge pins, Bare Stainless Steel Cable (SSC) does the job. Not recommended for use with deep troughing idlers over 35 º.

NAC - Nylon Covered Armored Cable

The right hinge pin for many mining conditions is the Nylon Covereed Armored Cable (NAC). Long service life is due to the patented hinge pin design. It combines a durable, flat wire wrap around the cable which is covered by nylon for smooth operation.

Note: Bulk fastener sets, replacement bolts and nuts and extra hinge pins are available. Please call our TFE Customer Service Department for availability.

Bolt Hinged Installation Tools and Supplies

Curved Templates

Used in conjunction with the “clip and gauge rod” method to install complete joints, the templet acts as a guide to accurately punch or drill holes into the belt ends. This insures proper fastener alignment.

Templets are available for all sizes of Bolt Hinged fasteners. They come in lengths for standard belt widths. See table below for ordering information.

Hand or Power Tools for Bolt Hinged Fasteners

In addition to a templet or aligning holder, 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 (a different wrench is required for stainless fasteners, which are furnished with slotted nuts); and a bolt breaker.

A power impact wrench cuts application time to 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.

The Ready Set Staple System

With the Ready Set Staple fastener system, an extended plate design separates the point of staple penetration from the line of belt flexing, thus eliminating splice fatiguing that results from sawing action at the point of attachment.

High tensile, stainless steel staple fasteners are furnished in strips with a bridge between each fastener plate. This strip design prevents individual parts from getting into the product being conveyed – eliminating a problem that may occur with some hook or teeth types of fasteners. The Ready Set Staples provide a strong splice, resistance to impact damage, and a smooth, unrippled joint that makes hinge pin insertion easier.

Ready Set Staples work between carcass fibers without severing them. Staples are hammer-driven through the belt, then clinched cross-wise to the belt, so that belt tension does not pull against the staples to unclinch them.
