FastenMaster LedgerLOK structural screws are engineered to fasten deck ledger boards securely to rim joists, replacing the need for traditional lag screws and through-bolts. These 14 x 5-inch fasteners are designed for outdoor construction and repair projects where structural connections must meet building codes and withstand long-term performance demands.
Whether you’re a professional contractor or a homeowner tackling a deck, fence, or other outdoor structure, LedgerLOK screws deliver reliable fastening in pressure-treated wood applications.
