The LedgerLOK Flat Head - Bucket of 250 has a wide flat washer head that installs flush to ledger for easier joist hanger placement. The code-compliant structural wood screws are engineered to fasten a deck ledger board to the rim joist of a house with no predrilling. LedgerLOK replaces lag screws and through-bolts, has been coated with a proprietary three-step coating process that protects against corrosion (even in pressure treated wood) and is ACQ approved. The built-in washer head eliminates the need for an additional washer, saving time and money. The LedgerLOK Flat Head with TORX ttap drive system installs flush to the ledger installation saving additional time and money. Use the traditional 3-5/8" for single ledgers and the 5" for double ledgers and thicker applications.
