Injection Molded Parts Bolt and Nut

Plastic insulated screw is a type of fastener that combines a metal screw with a plastic insulation or coating. This unique design offers several advantages over traditional screws, particularly in electrical and construction applications.   1. Electrical insulation: The plastic coating serves as an insulating material, preventing the metal part from conducting electricity. This makes it suitable for use in electrical installations where there's a risk of electrical shock or interference, such as when attaching wires to electrical boxes or conduit.   2. Heat resistance: The plastic insulation can provide thermal insulation, protecting the metal thread from heat, which is beneficial in high-temperature environments or when dealing with electrical components that generate heat.   3. Chemical resistance: Depending on the type of plastic used, these screws can be resistant to chemicals, making them ideal for applications where they may come into contact with corrosive substa…
