It's a standoff: you against a stubborn screw that won't budge. When you're sailing through a project and then come to a standstill, it can be exasperating. However, don't lose hope, because there is a solution for removing stuck screws. Gather your composure and look inside your toolbox for some of your most basic tools to assist you. Soon you'll be able to complete your project.
Push the pointed end of a nail through the slot on the top of the screw. Doing this will remove paint or crusted dirt so the screwdriver will fit snugly into the slot.
Select a screwdriver with the correct size tip and a square shank. The shank is the metal part of the screwdriver.
Place a wrench as near the bottom of the screwdriver as possible and still have it on the square part of the shank. Adjust the grip of the wrench until it holds tight to the screwdriver.
Push firmly on the screwdriver with your palm, while turning the wrench counterclockwise with your free hand. The added leverage and torque will remove the screw.
An impact screwdriver is a speciality tool for removing screws. The bottom holds the screwdriver bit and a spring separates the bit from the top of the tool. Hitting the top with a hammer compresses the spring, which then turns the bit. Home improvement centres sell impact screwdrivers.
Always use the correct size screwdriver to avoid damaging the screw slots.
