Daggerz™ Dagger-Lok wood screws are a high quality screw designed for general wood fastening applications. This screw features a flat head with nibs and a large shoulder under the head to prevent pulling through softer materials. The deep threads provide maximum holding power in softwoods and hardwoods. The pozi drive has increased torque without the risk of cam-out. Additionally, the zinc finish is recommended for installations in dry interior environments only. These screws work great in most woods, including hardwoods and plywoods.
