LedgerLOK is the first wood screw engineered to fasten a deck ledger board to the rim joist of a house with no predrilling. This easy to install structural screw 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 a code approved deck ledger board fastener that replaces lag screws and through-bolts.
