Using these DAGGER - LOK wood screws is easy. First, pick the right spot on your wood where you want to insert the screw. Since these screws have a Type 17 point, you don't have to pre - drill. Just place the screw on the spot and start driving it in with a #2 Square driver. The deep threads will give a strong hold in both soft and hard woods. The nibs under the flat head will keep the screw from spinning around and help it sink in by itself. As for maintenance, try to keep them dry to prevent rust, even though the black oxide finish offers some corrosion resistance. If you're using them in a very wet or damp environment, you might want to add an extra protective coating. Also, make sure to store them in a cool, dry place when not in use to keep them in good condition.
