Fastenmaster FMLL358-50

FastenMaster LedgerLOK is the original structural wood screw engineered to fasten deck ledger boards to a home’s rim joist without predrilling. Designed to replace traditional 1/2" lag screws, LedgerLOK delivers faster installation, higher structural performance, and reliable code-compliant fastening backed by ICC-ES ESR-1078.

LedgerLOK is available in both the classic hex-washer head and the NEW Flat Head TORX ttap Drive System, offering superior bit engagement and a stable, wobble-free drive. The advanced ProjectLife corrosion-resistant coating is ACQ-approved and guaranteed for the life of the project when installed according to FastenMaster guidelines.

Engineered for exterior deck construction, LedgerLOK eliminates the slow, labor-intensive process of predrilling lag screws while delivering exceptional strength and long-term durability. (Not recommended for use within 1000 feet of saltwater.)
