Decking Screws

Decking Screws

Decking screws are long, thin screws that are specifically made for outdoor use in all weather conditions. They are usually used to join and secure wood boards together, and are able to drive into wood easily. Decking screws get their name from their most common application—connecting wooden joists of outdoor decks. They are able to be countersunk, which is when a screw lays smooth against the surface of the material in which they are securing, which prevents snagging on the screw. They are made of carbon steel, alloyed steel and copper, all corrosion resistant metals that fare well in harsh conditions and low temperatures.

They are always finely threaded, which travels up all or most of the shaft. 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. 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. They are often coated to stop corrosion and rusting, and are available galvanized, ceramic coated or with high copper content.
