Any torquing to set values,or freeing of seized fixings,and you will need bits,on 3/8 or 1/2 socket adapters.
Snap-on make some of the best there are. The separate keys are fine,but limited access,your going to end up using a tube on the short end,and the ball end types will knack.
Being a tool tart,i would recommend having ALL types,but when needing to deal professionally,with hex,spline and torx,you want the very best available. Cheap tools never look so,when that fixing knacks,and you have to come back with a real one!
