My dad gave me this advice a long time ago when I moved into my first apartment. He even came out and changed the screws for me as soon as I moved in. Someone else recently posted about it and I thought I would share! A good home security tip that you may have never thought about.... Most contractors install the plates with the supplied screws which are only a half inch long and come out with one kick by a burglar. He installed 4 inch screws in their place that go through the door frame and into the framing of the house. They can kick for a long time before they get tired! You can see in the picture the screw in his hand is the screw supplied with the door hardware. Making a burglar make a bunch of noise and be foiled in their initial plan can not only give you time to arm yourself but they will most likely move on to an easier target.
