A design pattern composed of two to eight Riv-Nails allows for the fasteners to be clinched for maximum pull-out resistance — as the pilot nails do not cut the fabric, but divide it, and allow the rivets to slide between fill and warp yarns. The Riv-Nail is a compression fastener and, as such, does not rely entirely on the belt fabric for resistance to fastener pull-out.
Rivet Hinge Fasteners are used for major applications that require high strength and small pulleys. These include construction equipment, agriculture, wood products, and mining. Underground mining makes extensive use of these products for conveyors and structures that are extended or withdrawn in the course of mining. All fastener strips are sold one set per carton.
Rivet Hinge fasteners are available in R-2, through R-8 sizes, which fit belts 1/8″ – 3/4″ thick. The fastener strip is cross-scored so it can be easily broken by hand to fit any belt width.

Steel Conveyor Accessories uses special grades of high-strength steel that have been annealed for extra durability. These grades may yield 25 to 35% greater tensile strengths and have improved properties for long life and wear, compared to some steel fasteners. The R-2 and R-3 are made of galvanized coated steel, while TR-4, R-5, R-51⁄2, and R-6 are fully plated with a zinc “silver” luster to protect all surfaces of the metal.
There are many grades of stainless steel, each having properties that enhance the service life of conveyor belt fasteners. CAI uses three different designations:
- RLC is available for RLC-5, RLC-5 1/2, and RLC-6 fasteners. This low-chrome material offers enhanced benefits over regular steel for wear and corrosion.
- RC/TRC is high-chrome stainless plus nickel for high-wear areas and acidic conditions. The RC or TRC series can also be used on magnet belts.
- RS is the most non-magnetic grade, available for RS-2, RS-3, TRS-4, and RS-5. All stainless rivets are made of 430 SS, which may exhibit some magnetic properties because of the mill rolls or dies that were used to produce the material, but this is typically not a problem for magnetic belt applications.
Durgard is a special heat-treated steel with abrasion-resistant characteristics that provide several times the life of standard steel. Durgard Plategrip fasteners are not recommended for use in highly corrosive environments, but are instead specially formulated for abrasive situations.
