    Q:I need to remove my security bars on my windows to replace the windows but i do not have the tool to remove the screws.

    Answer This Question

    A:  Dave, The removal tools are difficult to find, and must be specifically sized to the screw head to work properly, and success is not certain. Another method is to cut a slot into the head of the screw for use with a flat head screwdriver. Someone would need to use an electric hand held grinder with a cutting wheel to establish a modest slot. Thank You, Grisham Bros.
