Ever run in to the problem where you have a 1/4-Inch drive socket and only can find your 3/8-Inch ratchet? That's where a set of drive adapters would come in handy! They will make your socket fit your wrench, and get you into the spaces you need. Have you ever be in the situation where you need to get around a few things to get a bolt out? Having a set of universal joints can be handy by allowing you to work around things.
