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;
