Specify the connection as a complete set: fiberglass threaded rods, matching nuts, washers and molded fittings for industrial FRP assemblies. Compare the catalog range and send your joint requirements for a project quotation.
FRP / GRP hardware brings composite material options to profile connections, equipment supports and access assemblies. Start with the component family, then define the dimensions and service conditions of the whole connection.
UNC thread series
All-thread rods for assemblies where the resin must be matched to chemical and wet-service exposure.
3/8″–16, 1/2″–13, 5/8″–11, 3/4″–10 and 1″–8 UNC; nominal lengths 4 ft and 8 ft.
Specify thread, cut length, matching nuts and service conditions.
Quote vinyl ester threaded rods
Metric thread series
Metric composite rods for project connections and insulating assemblies, with electrical requirements reviewed for the selected grade.
M8, M10, M12, M16, M20 and M24; nominal lengths 1.5 m and 3 m.
Confirm pitch, tolerance and nut engagement on the drawing.
Quote epoxy threaded rodsMatch the complete thread
Hex nuts in metric and UNC series, with polyester (UP), vinyl ester (VE) and epoxy (EP) material options for review. Ask about square nuts and bolt-and-nut sets for your drawing.
Metric: M8, M10, M12, M16, M20, M24. UNC: 3/8″–16 through 1″–8 in the listed rod series.
Confirm nut height, bearing face, resin and compatible rod or bolt.
Quote frp nuts & matched assemblies
Bearing & interface details
Flat composite washers offered in UP and VE materials. Select the complete washer geometry with the fastener and supporting surface.
Catalog diameter labels: Ø9, Ø11, Ø13, Ø17, Ø21 and Ø26.
Confirm bore, outside diameter and thickness; the catalog labels alone do not define the finished washer.
Quote frp washers
Drawing-based selection
Molded connection pieces for tube and profile assemblies. Send the mating section and connection drawing to review fit, fastening and tooling.
Geometry, wall thickness, hole layout, color and molding requirements by approved drawing.
Review the whole connection and required tests before release.
Quote molded frp fittingsOne connection, one parts list
Send the rod or bolt, nut and washer requirements together. Add the mating profile and a marked connection sketch so the interfaces can be checked in one review.
Include quantities per size and any packing or assembly requirements.

Custom lengths can be reviewed. This table is a size reference; connection capacity, electrical performance and installation torque require documents for the supplied configuration.
GRP means glass-reinforced plastic. The FRP fasteners on this page use glass reinforcement, so fiberglass fasteners, GRP fasteners and GFRP fasteners refer to the same material family here. The resin, reinforcement and finished component still need to be specified.
No. Match the thread system, diameter, pitch, tolerance and engagement length. A similar outside diameter does not make metric and UNC threads compatible. Request a matched rod, nut and washer set when the connection is being specified together.
Do not assume a size-for-size replacement. The joint needs its own review of tensile and shear demand, thread engagement, bearing area, creep, temperature and installation procedure. Provide the existing connection drawing and loads for assessment.
Use the installation procedure approved for the supplied rod or bolt, nut, washer and joint. A generic steel-bolt torque table does not establish a suitable FRP installation torque. Request the applicable tightening limits and supporting test data with the quotation.
The grating clips linked from this page are 316 stainless-steel hardware for FRP panels. Molded grating uses the M/C/J selection guide; pultruded grating uses M/J/T. These metal clips do not make an electrically insulating connection.
Yes. Send the drawing, dimensions, quantity, resin or exposure conditions and delivery destination. F1 will confirm available sizes, tooling, sample requirements, minimum order quantity and lead time in the quotation.
Send the joint, the materials and the parts list with the destination. Attach the drawing on the inquiry form so the complete supply scope can be reviewed. We reply within one business day; a formal quotation follows once the specification and delivery are reviewed.
