Does anyone sell a large selection of different sized nuts and bolts in one go, want to restore the underside of my car in the summer and might as well put new ones on whilst the engine is out and everything is unbolted underneath, but all I can find is say a box of 100 in each size, surely there is an easier way to buy for this sort of thing?

Also if there isnt an easier way, then what pitch are standard ford nuts normally?

Help appreciated
