Yes,metric & for the hex sockets,they will usually come in a set.The common sizes you will use are 2,4,5,6,8mm.For the normal sockets if you buy the 3/8drive set in metric,it will have all the sizes you need:thumbup:
G'day mate,I'd start with a Good quality 3/8 drive socket set,screw driver set,3/8 drive hex sockets(allen key in socket config) an oilfilter removal tool & if you can afford at the same time a 3/8 drive torque wrench :thumbup:
