Riv-Nails
A design pattern composed of 2 to 8 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.
Specifications
Rivet Hinge fasteners are available in R-2, R-3, R-5, R-5 1/2, R-6, and R-8 sizes which fit belts 3/16" - 3/4". The fastener strip is cross-scored so it can be easily broken by hand to fit any belt width. First, determine the size and metal specifications.
Improves the installation of hinged rivet fasteners on newer, synthetic high strength belt fabrics. Manufactured with special tempered steel to form the beveled ends and yield a smooth, low profile
Metal specifications
Steel
Sunnforest uses special grades of high-strength steel that have been annealed for extra durability. This special grade yields 25 to 35% greater tensile strength and has higher hardness for longer life, compared to some other steel fasteners. R-5 and R-6 are zinc coated “silver,” whereas R-3 and R-5 1⁄2 are zinc coated with zinc dichromate to give it a “gold” color for easy identification.
Stainless Steel
There are many grades of stainless steel, each having properties that enhance the service life of conveyor belt fasteners. Sunnforest 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.
