Multi-material No. 8 Label X 1-1/4 In. L Unidrive Flat Head Serrated Construction Screws

The Spax No. 8 x 1-1/4 In. Flat Head Multi-Purpose Screw is a versatile fastening solution designed for a wide range of interior construction and assembly projects. Whether you're working with wood, concrete, masonry, sheet metal, or plastic, these zinc-plated steel screws deliver reliable performance and a professional finish.

These screws solve common fastening challenges by combining a flat head design with a Phillips/Square combo drive system. The flat head allows materials to sit flush with the surface, creating a clean, finished appearance without protruding fasteners. The dual-drive feature—compatible with both Phillips and Square drive bits—eliminates the need to switch tools and reduces frustration from cam-out during installation.
