Denny...you can get hex drives / sockets much larger than that
If you hunt around, you'll find sets that carry larger sizes, which will probably save you money if you're interested in buying your own.
Not sure what your budget is....top end Snap-on or mid range Kohn...
Here's a link to one supplier for a single hex drive..

But...if you look around, there are some excellent german kits that come in a case too.
