3/8 is also the larger sized standard tripod screw size - you might have a tripod head or camera with a female thread to test it on. Since you are in Germany, going to a hardware store to match may not be an option like it is in the US (which is what I have done with underwater gizmos for DIY projects) but maybe try automobile parts stores catering to US cars (if such exists).
