I recently tried to fit a pannier rack onto my hercules commuter, to do so I had to remove the mudguard an re-fit it with the rack supports. In the process the old, rusty bolts just snapped so I need to replace them but don't know the name of the bolt. Here's a pic, cheers.

Ride hard or ride home alone!
there are several different sizes and types of these, take it to your LBS, they may have them in stock.
I'm not sure the denomination of money, but I will say they should be rather inexpensive!!!!
Good maintenance to your Bike, can make it like the wheels are, true and smooth!
This shouldn't be so expensive i use it for my bicycle but i have forgotten its price actually go to your near by store if you have any old peace show to them and they would give a new one to you
