    OK, quick and odd question - what is the license plate bolt size?

    I pick up my Prius this week, and I'm transferring plates that I'm bringing to dealer. I attach plates to my cars using stainless steel hex head bolts and want to bring these with me. Most cars seem to be M5 or M6, and only a short couple cm length is needed.

    Thanks

    i cannot answer your question but did the front plate kit only come with two screws
    in your car?

    i know mine only came with two when in reality you need four to make things work.
    i simply asked the dealer for two more when i visited after buying the car and had
    the plates in hand.

    sorry to interrupt your thread but i am guessing you did not get them either!?!

    I happen to have a Toyota license plate screw here on my desk at work, which I took from a dealership last week, for some odd reason.

    The threaded part is 5/8" long exactly. The outside diameter of the threaded part is 7/32". The head of the screw is 6/32" tall. Maybe you can test out some bolts on a friend's Toyota.

    The thread diameter is 6mm. The required length varies depending on your frame.

    EDIT: Note - I believe most foreign cars use a 6 mm diameter thread, while most American cars use a 1/4 inch diameter thread.

    Perfect, thanks.

    So it appears to be M6-1x20mm.

    Why are there only two holes in hatchback for screws? I would love to use 4 screws, any way to do this myself safely?

    For both the front and rear license plates, the license plate attaches via the two top screw holes.

    I use four screws. For both the front and rear license plate bottom two screw holes, I use a shortened plastic screw and nut. In addition, for the rear I use a pad so the screw and nut do not scratch or dent the metal.
