    A Pain In The Ass, aka PITA.






    I've never actually seen one like that. Interesting. Will regular square bit fit?

    I knew I could depend on you guys.

    It looks like it could stand a lot more torque backing out than driving.

    A Sawzall will turn it into a regular screw head.

    Security screw - used to discourage item fastener is holding from removal with common tools. Works for a short period of time, then the bits are sold in hardware stores...

    Doesn't look very secure, it looks like a multiple of bits could crack that one, should be called unihead.

    From what I've seen,they are used for wood decking, and I'm guessing other things. Found them holding wood floor to the steel carriage of my enclosed trailer. Am guessing they were used there for speed of assembly.
