    Alpa thread hole sizes

    Does anyone know the thread hole sizes on an ALPA/ALPA FPS camera. I know the center is 3/8ths but what are the other two sizes that are both on both sides of the 3/8ths hole.

    Thanks,
    Mark

    The inner smaller holes have no thread . They are for the "safety pins" to prevent an attached accessory from turning , when the 3/8 center screw should have come loose . That never happened to me .
