Spare mixed bolts/nuts Car Bike (Sherwood NG5)

Hi all,
I'm doing up an old project and I'm a bit short on fasteners. Does anyone have an old jar or tin of mixed metric bolts, nuts, and washers they want to get rid of?
I mostly need standard M6 and M8 threads. Car bolts or motorcycle bolts are all fine, I just need the threads to match! I really don't mind sorting through a messy or mixed box.
Happy to collect locally. Thanks!
