Faster and Stronger Than 1/2" Lags
FastenMaster’s new engineered fastener is the first designed to attach a deck ledger board to a house without predrilling. These heat-treated screws provide higher shear values than traditional 1/2" lags. Use a 5/16" hex nutdriver with our 14.4v Makita Impact Driver or a 1/2" corded variable speed drill to drive these screws. A proprietary multi-coat finish is guaranteed not to rust for the life of your project, even in ACQ treated lumber (saltwater applications excepted). A 5/8" dia. washer head prevents the fastener from countersinking into the wood. Consult your local building codes for appropriate use. LedgerLok meets ICC AC233. Made in USA.
