The Midwest Fastener SaberDrive 54984 Structural Screw is engineered for demanding structural and framing applications where strength, durability, and installation efficiency are essential. Designed for both residential and commercial construction, this premium structural screw provides exceptional load-bearing performance and reliable fastening in dimensional lumber, engineered wood, exterior building materials, and treated wood environments.

Constructed from high‑quality hardened steel and finished with a durable black XL1500 or Platinum protective coating, this screw resists corrosion and environmental wear, making it suitable for interior or exterior projects. Its Type 17 self‑tapping point, aggressive serrated threads, and Star/Torx drive system ensure faster penetration, reduced splitting, and superior driving stability with minimal cam‑out. These properties make the 54984 model a preferred choice among contractors, carpenters, and structural installers who need a dependable alternative to traditional lag screws.

Whether you're building decks, securing heavy timbers, installing ledger boards, or working on engineered structural assemblies, the SaberDrive 54984 delivers professional‑grade fastening power with consistent results.
