LedgerLOK is the first fastener engineered to attach deck ledger boards to the rim board of the house with no predrilling. No need to predrill and hand-ratchet in 1/2 inch galvanized lags and washers. LedgerLOK also has stronger shear values than 1/2 inch galvanized lag screws. Plus, with LedgerLOK's smaller shank diameter, even a cordless drill (14.4 volts or higher) zips them right in, saving on battery life and additional tooling costs. Each pack size contains a free 5/16 inch driver bit. LedgerLOK fasteners are American made.
