- Product Introduction — Precision-manufactured to meet structural fastening requirements, these #9 x 2-1/2" screws are classified as SD (structural drive) connector screws. The 1/4" hex drive allows for high-torque installation with impact drivers, while the integrated 0.380"-diameter washer face prevents embedment into softwoods and maintains clamp load over time.
- Process Insight — Mechanical galvanizing deposits a uniform zinc layer through a cold impact process. Unlike hot‑dip galvanizing, it won't distort threads; unlike electroplating, it offers consistent thickness and no hydrogen embrittlement. This means you get a screw that's tough, ductile, and ready for decades of service.
- Applications At A Glance — Perfect for joist hangers, rafter ties, beam connectors, and other structural hardware. Use them on decks, porches, sheds, fences, and interior framing. The 2-1/2" length is ideal for fastening 2x lumber (actual 1.5" thick) into solid beams or rim boards.
- Long Lasting — The SD screw features a specially designed shank. Optimized heat treatment gives it greater ductility and strength for reliable performance under tough conditions.
- Quantity Included — 100 pieces per box enough for a typical residential deck or multiple smaller home improvement jobs. Bulk packaging saves money and reduces trips to the store.
