Heavyweight Lace Fasteners

Fastener Selection Chart

Your belt’s characteristics will determine which lacing fastener should be used. Belt Power created this chart to help you select the most suitable fastener for your specific application.

Bolt Solid Plate

Flexco® Bolt Solid Plate fasteners are engineered to meet the demands of the toughest material handling applications, providing a strong, sift-free splice with superior holding ability. A choice of sizes accommodates belts from 3/16” (5 mm) to over 15/16” (24 mm) thick.

Bolt Hinged

For belt conveyor applications subject to frequent length adjustments, the Bolt Hinged fastener is easy to install – and re-install. The joint can be separated simply by removing the hinge pin. On-site installation requires hand or power tools. Our exclusive piloted bolt also simplifies installation and holds fastener plates firmly in place. For added strength and pull-out resistance, specially formed teeth penetrate deep into the belt carcass without damaging carcass fibers.

Market applications:

• Construction and Road Equipment
• Coal
• Salt
• Potash
• Grain
• Wood Products
• Recycling

Solid Plate

Ideal for pulley diameters as small as 14” (350 mm), the 6-rivet configuration provides a staggered, multiple-point rivet attachment to allow rivets to pass between carcass fibers without severing them for maximum resistance to pull-out. Plus the patented Scalloped Edge™ provides for a lower fastener profile to extend belt splice life and reduce exposure to belt cleaner blades and other conveyor components.

Rivet Hinged

The Flexco® SR™ Rivet Hinged Fastening System has earned a reputation for quality and performance in the most demanding material handling applications on earth. Wherever belt conveyors are used, you need a fastener system that lets you set up, splice, and get out of the way … fast. Flexco SR fasteners deliver the performance, long life, and easy installation that maximize belt availability and help keep productivity on a roll.

Market applications:

• Coal and Hard Rock
• Underground and Surface Mining
• Wood Processing
• Asphalt Plants
• Construction and Road Equipment

Super-Screw®

The SUPER-SCREW® is a flexible rubber splice with steel inserts for joining conveyor belts as an alternative to traditional vulcanizing. It has specific screws that are self-drilling and self-tapping (they spread the carcass threads without cutting them). Not only is the SUPER-SCREW® a great way to fasten the ends of a belt but it can also be used as a patch repair if material punctures the belt.

Advantages:

• Wear and cut resistant rubber
• Quick to install with no specific skills (save downtime & install cost)
• Installed under all weather conditions
• Eliminates the need to use expensive and heavy vulcanizing equipment
• Installed only with a cordless screwdriver
• Compatible with small pulley diameters with bias installation
• Super-Screw® splices are flexible, high tensile strength and leak proof
• No pre-drilling necessary, self-tapping screws
• Suitable for high-heat belt up to 392°F
• Excellent on textile or PVC solid woven belts (steel cord belts as an emergency)
• Perfect for tubular belts
• Used as a repair patch for punctures and belt tears
