These interior Construction Lag Screws replace traditional lag screws or carriage bolts. The star drive maximizes torque during installation and eliminates cam-out, while the washer head provides exceptional holding power. The Type 17 point and serrated threads eliminate the need for pre-drilling. SaberDrive® construction lags are stronger than larger diameter carriage bolts, lag bolts, and hex bolts, and install in a fraction of the time with a simple drill or impact driver. Use them wherever you would typically use carriage bolts, lag bolts, or hex bolts for wood to wood connections.
