#10 x 1-1/2“ SD Connector Screws, Joist Hanger Screws 1/4" Hex Head with 0.380"-Dia, Mechanical Galvanized,for Construction, Home Improvement (100PCS)

• Product Introduction — Precision-manufactured to meet structural fastening requirements, these #10 x 1-1/2" 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.
• 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.
