FastenMaster FastenMaster-FMLL358B-250, 3-5/8"From the ManufacturerSave time, money, and labor costs. 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.
