    Take the bolt out that holds the fuse box and match it up, it should be the same.

    Toyota use JIS standards.
    You can usually get a good idea by the head of the bolt.

    10mm head is 6mm bolt
    12mm head is 8mm bolt
    14mm is 10mm bolt

    So, if the bolt you tried was too big and it was a 12mm head.
    Than the next size down is a 6mm bolt.

    @ TnShooter
    Thanks. Great information. Makes sense the bolt for the fuse box is a 10mm which was small.
