If you are buying a socket set, for the smaller sizes I recommend 3/8" square drive which are lighter and handier than 1/2" square drive. They are very adequate up to 3/8" threads, or evn 7/16". You will find 1/2" square drive useful for larger sizes, and if you buy a torque wrench most have a 1/2" drive connection. Ever since a good friend recommended the 3/8" drive system I have been grateful to him, having used only 1/2" drive sockets previously. They both have their place and it is therefore useful having both. Experience will soon show which to use where.
