Deck screws are specialized fasteners designed for outdoor construction projects, particularly for building decks. They are typically made from corrosion-resistant materials like stainless steel or coated with protective finishes to withstand harsh weather conditions. Their sharp tips and threaded shafts allow for easy driving into wood, providing a strong hold that prevents loosening over time. These screws often feature a larger head than standard screws, which helps to distribute the load and reduce the risk of splitting the wood. Many deck screws also have a self-drilling design, eliminating the need for pre-drilling holes, making them a popular choice among carpenters and DIY enthusiasts alike.
