Decking Screws - Countersunk

Decking screws are a type of woodscrew with countersunk or hexagon (hex) heads that are commonly used for fastening timber decking to joists. They can also be used for other timber to timber applications.

A countersunk head is usually used when no part of the fastener head is required to be protruding above the level of the substrate. Countersunk heads can also be recessed and filled over if a hidden fixing is required. Usually abbreviated to CSK.

The green organic coating adds additional weather resistance, prolonging the life of the screw.
