An FRP bolting kit comprises fiberglass-reinforced threaded rods, hex nuts, and flat washers manufactured from vinyl ester or isophthalic polyester resin systems. The fully non-metallic composition provides electrical insulation properties, making these fastener sets suitable for installation in switchyards, substations, and transformer enclosures where non-conductive hardware is specified. Corrosion resistance is verified per ASTM D543.
Tensile performance of the threaded assemblies typically depends on rod diameter and resin matrix selection. Under standard mechanical testing, composite fasteners generally avoid thread galling issues common in stainless steel hardware. Installation torque limits differ from metallic fasteners and should follow manufacturer recommendations to prevent over-tightening. Service temperatures typically range from −40 °C to 80 °C, depending on resin selection, with the material retaining structural toughness across this operating window.
The glass-reinforced polymer matrix is inherently resistant to galvanic corrosion when installed in mixed-material assemblies. Low moisture absorption characteristics are commonly evaluated under ASTM D570, supporting dimensional stability in humid or submerged conditions.
Proven in Field
"A coastal substation retrofit deployed non-metallic FRP fasteners throughout transformer plinth assemblies, eliminating recurring replacement cycles previously caused by stainless steel crevice corrosion in salt-laden air."
