5/16 In. In. X 2-1/2 In. L Star Hex Head W-cut Structural Screws

GRK Fasteners RSS structural screws are engineered fasteners made of specially hardened steel, delivering high tensile, torque, and shear strength for demanding construction and woodworking applications. These screws feature sharp threads and points that bite instantly into material, including hardwood, while their design reduces the splitting effect caused by smaller shanks. With their efficient performance and reliable holding power, RSS screws serve as a strong alternative to traditional lag screws.

Whether you're building decks, installing ledger boards, fastening hinges, connector plates, or tackling other structural projects, these screws provide the reliability professionals and DIY enthusiasts need. The star drive design ensures better grip and reduces the likelihood of stripping during installation, while the washer head delivers a tight fit with zero-gap joints that enhance overall structural integrity.
