Omg Inc FMLL358-12 Ledger Screw 3-5/8 in 12 Pack

Product Description

The OMG INC FMLL358-12 is a structural ledger screw designed to attach a ledger board directly to the rim board of a house without pre-drilling. Sold in a 12-pack, each screw measures 3-5/8 inches in length. The LedgerLOK fastener is engineered to eliminate the pre-drilling step, reducing labor time on deck and ledger board installations. It meets IBC and IRC code compliance per ESR 1078 and is approved for use with ACQ-treated lumber, making it suitable for outdoor structural applications where pressure-treated materials are standard. Carpenters, deck builders, and contractors install this fastener in residential construction.

This screw is used in residential deck framing where a ledger board must be fastened securely to a house rim board. The no-pre-drill design speeds up the fastening process on wood-framed structures. ACQ approval means it can be driven into pressure-treated lumber without concern for accelerated corrosion typically associated with ACQ chemicals and standard fasteners. It is appropriate for new deck construction and ledger board replacement projects governed by IBC or IRC building codes.
