....one of those sockets that has a flat head screwdriver end to it. It's like turning your ratchet into a big screwdriver. I need it to fit a 1/2" ratchet. I have some flush screws about an inch wide that need to be taken off and the biggest screwdriver I have is to small. I have one of these sockets already but it's too big and, since I inherited it awhile back, I don't know where it came from. Thanks.
