A non-metallic shank is a metal-free wood screw, typically made of polyvinyl chloride (PVC), used in applications where traditional metal screws are unsuitable. Non-metallic shanks are highly resistant to corrosion and can be used in various temperatures and environments. They also offer excellent strength, durability and stability. As such, they are suitable for multiple applications, including decking, siding, HVAC and more. Non-metallic shanks can provide quick installation and adjustability with the benefit of being aesthetically pleasing. They are an excellent alternative to metal screws in many situations.
