FRP Fasteners

Our range of FRP fasteners are known for their superior quality and mechanical strength. FRP fasteners like FRP bolts, FRP studs, FRP nuts, FRP threaded rods, FRP bolts, etc. are being used for joining of Channels, Flats, etc. In chemical plants, fertilizer plants, off shore project, cooling towers, FRP fasteners are being used in joints instead of metallic or PVC fasteners.They are used wherein metallic fasteners are prohibited.These products are available in different dimensions as per the needs and specifications of different clients in various industries. 

Standard sizes available :

• Stud: M 6,8,10,12,16,20,24,25 mm
• Nut: M 6,8,10,12,16,20 mm
• Threaded Rod: M 6,8,10,12,16,20,25 mm

Also the above can be customized.

Advantages of FRP Pultruded Fasteners:

• Non- Conductive (electrically insulating)
• Transparent to electromagnetic waves
• High - Mechanical strength
• Low maintenance
• Corrosion resistant

Agni Epoxy Sheet is as per NEMA Grade FR-4/EP3 , with high mechanical strength at room temperature, good electrical properties under dry and humidity conditions, flame retardant, suitable for mechanical, electrical and electrical and electronic applications It is manufactured from electrical glass cloth that has been impregnated with epoxy resin under pressure and heat. used for the insulating spare parts of the electrical appliances and transformers. The grade is for class B/F.
