The hex size and bolt size are not necessarily related. I would say that it is more likely to be an 8 than a 7. You need to take the your bolt in and have it matched for thread diameter, thread pitch (the number of threads for a specified length), and threaded length, but in a magnetic material - you should take the Hexlox as well. The only 7 mm bolts that I have ever seen are the Nitto seatpost bolts - it is a rarely used size, which is why hardware stores don't carry them.
