LedgerLOK is a code-compliant structural wood screw 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 large hex-head allows for greater bit engagement, reducing cam-out.
• LedgerLOK is tested and supported by engineering data that conforms to the most current ICC standards. It is also approved for use in ACQ or treated lumber.
