#17×12″ CTX T-40 Bronze Construction Lag Screws




#17×12″ CTX T-40 Construction Lag Screws

The Superior Alternative to the Common Lag Screw

Heat treated and hardened, these screws are stronger and more durable than ordinary lag screws. They have deep cutting threads for quick, easy driving and a sharp notched point for exact, quick starting with less “walking”. A built-on round washer head with smooth edges gives a professional finish.
