Talk to any golf cart mechanic worth their salt, and they will tell you, if you are working on an EZGO, there are only a few different socket sizes you are going to need. Even if you were to take the whole buggy apart, you would primarily use just three different ones. That's why it is a great idea to identify those nut sizes that get repeatedly used on your TXT and throw not only those wrenches in a mobile toolbox that rides along with you but also a few of the nuts themselves, like the aftermarket 5/16" Steel Hex Nuts for golf carts.Keeping a handful of these babies can get you and your buddies out of more than one jam. This size nut is used all over the cart. It is honestly common on other models like Club Car DS's, Marathon's, and anything else made in the USA. Do yourself a favor and call Buggies Unlimited for a few spares. You will need them, and you know it!
