FastenMaster LedgerLOK FMLL005B-250 Structural Screw, 5 in L, Coarse Thread, Hex Drive, Steel

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.
