If it’s your first time looking for the most fitted wood screws for door hinges, you might be very confused. What size screws for door hinges will you need? Can you go for a random number?

Obviously not! The screw size will vary according to the type of hinges and door material. For instance, If you have a wood front door, choose number #9 between 1.5-inch and 2.5-inch long screws, depending on the door size and weight. Metal doors are super heavy and require large diameter number #12 screws. In contrast, a small diameter number #6 screws of 5/8 inches are perfect for loose cabinet doors.
