Nuts/bolts/washers for garden bench (DE72)

I'm looking to restore a garden bench and two chairs if possible with unwanted products. I need :
48 x M6 x 35mm bolts, washers and nuts for outdoor use for the chairs and
24 x M8 x 40mm bolts, washers and nuts for outdoor use for the bench.

Ideally, hex bolts (I think they are called) if possible. Does anyone have any of the above that they no longer need and were going to throw away?
