The LedgerLOK Flat Head - Bucket of 250 install flush to ledger for easier joist hanger placement. LedgerLOK Flat Head Structural Wood Screws also include a TORX ttap drive system to ensure a smooth and wobble-free installation.

LedgerLOK 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. Use the traditional 3-5/8" for single ledgers and the 5" for double ledgers and thicker applications.

All LedgerLOKs are guaranteed not to rust or corrode for the life of the project. The fasteners have also been tested and approved for use in ACQ including contact treatment levels. LedgerLOKs are not recommended for saltwater applications.
