Decking Screws
Decking screws can be made of carbon steel, alloyed steel (like stainless steel), copper and other metal materials; all corrosion-resistant metals that fare well in harsh conditions and low temperatures are candidates for use as decking screws. Compared to industrial fasteners and many varieties of other threaded fasteners, decking screws are fairly thin and finely threaded. Decking screws, like all screws, are important building materials. Choosing the right screw composition, thread count, length and even color all affect the functionality and attractiveness of the structures in which they are installed. It is important before beginning a project that involves decking screws to carefully consider every variable that will contribute to the screw's performance throughout its lifespan.
Decking screws are always finely threaded, and the threads travel up all or most of the shaft of the screw. They have a unique shank, which helps them stay in the right place during drilling. Deck screws also always have a head, which is stamped with slots made for screw drivers, usually in a crossed shape. Decking screws can also be designed for use with Allen wrenches, Phillips head screwdrivers and a wide variety of other tools. The ends of deck screws come to a sharp point, which makes it easy to drill into wood. Some even come lubricated, which eases the drilling process even more and reduces the chance of splitting, which is a common problem, especially with lower quality or dried-out wood. They are often coated to stop corrosion and rusting, and they are available galvanized, ceramic-coated or with high copper content. Stainless steel can be a popular decking screw material because of its strength and resistance to corrosion. Especially in environments where the screws will be exposed to changing weather conditions, stainless steel may be an appropriate choice. The right decking screw choice depends on the screw's intended application.
