Hex Head Cap Screws 40% Glass-Filled Polyurethane

Isoplast hex head cap screws are a type of plastic fastener made from fiberglass-reinforced polyurethane or Isoplast resin, prized for their high strength and exceptional chemical resistance, often used as a lightweight replacement for some metal fasteners.

• High Strength: With 40% glass fiber reinforcement, the material has a tensile strength of up to 27,000 psi, which is comparable to that of aluminum.
• Chemical Resistance: They resist a wide range of chemicals (pH range from 2 to 14), oils, grease, and solvents, making them suitable for use in corrosive environments where metal fasteners might fail.
• Corrosion Resistance: Unlike metal fasteners, they will not rust or gall. They are also resistant to sea water and UV radiation.
• Non-Conductive: The plastic material provides electrical insulation, which is an important safety feature in certain electrical or utility applications.
• Lightweight: They are significantly lighter in weight than metal fasteners.
• Impact Resistance: They offer high impact resistance and minimal creep.
