Omg Inc FMLL358B-250 Ledger Screw 3-5/8 in 250 Pack

Product Description

The OMG INC FMLL358B-250 is a structural ledger screw engineered for attaching a double ledger board to a house framing member without pre-drilling. Each screw measures 3-5/8 inches in length and is designed to replace a 1/2-inch lag bolt in ledger-to-rim-joist connections. The fastener is ACQ approved for use with pressure-treated lumber and carries ESR 1078 code compliance under IBC and IRC standards. This 250-pack is suited for decking contractors, structural carpenters, and framing crews working on residential deck ledger installations where code-compliant connections are required.

This screw is used in residential deck construction and structural ledger board applications where a ledger board must be securely fastened to the house band or rim joist. The no-pre-drill design speeds up installation on double ledger assemblies. Its ACQ-treated-lumber approval makes it appropriate for exterior applications where preservative-treated wood is specified by code. The 250-count package quantity supports production-level deck framing jobs.

Installation Notes

Installation is performed by licensed carpenters or qualified framing contractors working under applicable IBC or IRC structural requirements. Power down any adjacent electrical systems and ensure the work area is clear before driving fasteners into rim joist assemblies. No pre-drilling is required, but confirm lumber species and connection geometry meet the load tables published under ESR 1078 before specifying fastener spacing. Always follow local building department requirements and inspection protocols for structural deck ledger connections.
