The OMG INC FMLL005-12 is a 5-inch Ledgerlok structural screw designed to attach a ledger board directly to the rim board of a residential structure without requiring pre-drilling. Supplied in a 12-pack, these screws are IBC/IRC code compliant under ESR 1078 and are approved for use with ACQ-treated lumber. Licensed contractors and framers rely on Ledgerlok for deck ledger connections where code-compliant fastening is required without the added labor of pre-drilling pilot holes.
The FMLL005-12 is suited for residential deck construction and structural ledger-to-rim-board connections. The screw's engineered design allows direct installation into treated and untreated dimensional lumber, streamlining the fastening process on new deck builds and ledger replacements. ACQ approval makes these screws appropriate for use in exterior applications where pressure-treated lumber is specified by code or project requirements.
Designed for structural ledger board to rim board connections in residential deck construction using dimensional lumber, including ACQ pressure-treated wood.
Installation is performed by licensed carpenters or framers following IBC/IRC deck ledger connection requirements. No pilot hole is required, but confirm lumber species and thickness comply with the ESR 1078 evaluation report for the intended connection. Use an appropriate bit and impact driver rated for structural screws. Always consult local building codes and the applicable evaluation report before finalizing fastener schedules.
