SPAX® Multi-purpose construction screws are the versatile fastening solution for a wide range of interior and exterior applications in multiple materials including wood, concrete, masonry, sheet metal, plastic and treated lumber. Proprietary HCR-X coating is approved for use in treated lumber and freshwater environments. Note: Not for use with redwood or cedar.

A patented MULTIhead design featuring ribs on the underside of the head facilitates a clean, flush or countersunk finish in wood and acts as a brake against metal hardware to prevent stripping out. Exclusive T-STAR plus drive offers superior bit fit to eliminate camming out. These fasteners are ideal for overhead work and are available for both interior and exterior use.
