TRU-RIVET HINGE FASTENERS
A design pattern composed of two to eight Tru-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 Tru-Nail is a compression fastener and, as such, does not rely entirely on the belt fabric for resistance to fastener pull-out.
Tru-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 Underground mining makes extensive use of these products for conveyors and structures that are extended or withdrawn in the course of mining.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.

R2 Tru-Rivet Fasteners make installation a breeze! You get an advantage over the 375 nut-and-bolt design, where holes must be aligned and punched before installation begins. Plus, the use of fewer rivets translates into additional material and labour savings. R2 rivet fasteners are available in both galvanized and stainless steel.

R3 Tru-Rivet Fasteners
R3 Tru-Rivet Fasteners provide fast installation! Consider the advantages over 375 and 550 nut-and-bolt design, in which holes must be aligned and punched before installation begins. With the R3, there are 40% fewer Tru-Nails than with the larger R5 version. All this means material and labour savings.

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 R2 and R3 are made of galvanized coated steel, while R5, R51⁄2, and R6 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 RLC5, RLC5 1/2, and RLC6 fasteners. This low-chrome material offers enhanced benefits over regular steel for wear and corrosion.
- RS is the most non-magnetic grade, available for RS2, RS3 and RS5. 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.
- RC is high-chrome stainless plus nickel for high-wear areas and acidic conditions. The RC series is a non-magnetic solution which can also be used on belts that are exposed to magnetic elements in order to avoid materials clumping together and putting the conveyor system at risk.
