What are posidrive screws?
>the right tool. Clarke later added: Posidrive has eight “crosses” rather than four as on a Phillips. It is thinner and longer than a Phillips. One of the “plus” patterns in the Posidrive is pretty thin. If you will look at the large screws fastening the hinges to the bulkhead and doors, you can see the second “plus” pattern quite plainly. Snap-On has Posidrive. I expect Craftsman probably does too but don’t know that for sure. I would suggest getting Number 1 and Number 2 Posidrive as classic “screwdrivers” and Number 3 and Number 4 sizes (used for the large screws in the hinges) as 3/8″ drive sockets. My 3/8″ tool set includes a screwdriver-type handle for Torx, Posidrive, Phillips, etc sockets.
