## Description

LedgerLOK is the first wood screw engineered to fasten a deck ledger board to the rim joist of a house with no predrilling. The built-in washer head eliminates the need for an additional washer, saving time and money. The large hex-head allows for greater bit engagement, reducing cam-out.

• Flat head for flush finishing on wood
• Sharp tip doesn't require pre-drilling
• 3-step coating process resists corrosion
