Product Description

GRP FRP fiberglass bolt and nut

1. Epoxy Slotted Flat Head countersunk screws And Nuts    
2. Epoxy FRP U bolt 
3. Epoxy fastener bolts and nuts,Threaded Rod, Washers

The composite material bolts (screws) produced by our company use glass fiber as the reinforcing material and epoxy resin as the matrix for fasteners. The products include screws, bolts, nuts, and washers, which are processed by mechanical machining or other forming methods. The product has high strength, excellent insulation, outstanding weather resistance, and outstanding corrosion resistance. 1, Application scenarios of composite material bolts (screws): 1. Connection of mechanical components; 2. Connection and installation of power facilities and equipment; 3. Petrochemical, marine, pharmaceutical, etc; 4. Aerospace, ship, vehicle components, etc;

Usage to replace Stainless steel (SS)

Advantage:
1. High Strength and Corrosion-resistant Performance in Sea water
2. Using FRP composite bolts, making the entire installation in Electrical Industry completely non-conductive.
