I had the shop do mine since I was in for inspection, but this is good info to have. Some people don't have a fleshed-out toolset yet and these nuts are all a bit larger than the common set the beginning DIY-er would likely pick up. Definitely a good reason to get a full-featured set; either as a whole or piece by piece (Sears sells Craftsman, Lowe's Kobalt, and Home Depot's Husky all sell individual wrenches for example). If the cost can't be justified, a couple of knuckle-buster (crescent wrenches) that have a nice-sized jaw can do in a pinch, though not as handily.
