Omg Inc FMLL358-50 Ledger Screw 3-5/8 in 50 Pack

Product Description

The OMG INC FMLL358-50 is a structural ledger screw engineered for attaching a ledger board directly to the rim board of a house without pre-drilling. Sold in a 50-pack, each screw measures 3-5/8 inches in length and is manufactured to meet IBC and IRC code requirements under ESR 1078. The fastener is also approved for use with ACQ-treated lumber, making it suitable for exterior deck and ledger applications where treated wood contact is a concern. Licensed contractors and experienced deck builders are the primary installers of this screw.

This screw is designed for residential and light commercial deck ledger connections where a direct, code-compliant attachment to the rim board is required. The no-pre-drill design reduces installation time and labor on standard framing lumber. It is commonly used on new deck construction and ledger replacement projects where IBC or IRC compliance must be documented.

Installation Notes

Installation is typically performed by licensed carpenters or deck contractors following IBC or IRC framing requirements. No pre-drilling is required, but verify that the substrate lumber species and thickness conform to the ESR 1078 evaluation report before installation. Use appropriate driver bits rated for structural fasteners and ensure the connection point is accessible and the framing is properly aligned before driving screws. When working with ACQ-treated lumber, use only compatible hardware to prevent accelerated corrosion at the connection.
