Big Timber 1CTX145 T-25#14 x 5' Construction Lag Screw Knurled Shank Type-17, B OJ_FENUBSHE

These construction lag screws are heat treated and hardened. They 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 fnish.
