FastenMaster LedgerLOK FMLL358-50 Screw, 3-5/8 in L, Coarse Thread, Hex Drive, Self-Drilling Point, Steel, Epoxy-Coated, 50/PK

LedgerLOK is a code-compliant structural wood screw engineered to fasten a deck ledger board to the rim joist of a house with no pre-drilling. 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.
