SPAX construction screws are versatile fasteners engineered for multi-material applications. These #8 x 2-1/2 inch flat head screws work in wood, concrete, masonry, sheet metal, and plastic, making them ideal for framing, securing fixtures, attaching trim, and general fastening tasks. The flat head design sits flush with the surface for a clean, finished appearance suitable for both visible and hidden applications.

The Unidrive combination head accepts both Phillips and square drive bits, giving you flexibility with common tools already in your workshop or jobsite.
