I have an old bike with Sugino crank and have lost two bolts and bolts, on the bolt thread 8 mm long and then has a 3.5 mm larger bulb the width of the head is 7.9 to 8 mm. Any ideas on where I can source?

2. Google "Sugino chainwheel bolts" and see if you get a match (add the model name/number if you can determine it). If not you could try calling one of the suppliers that comes up in a search to see if they carry what you want.
3. If there's a bike co-op or used bike shop locally see if they have compatible parts
No matter what it's time to check the other chainwheel bolts for tightness, as well as other securing bolts on the bike before you loose more. There would have been symptoms (clicking, rattling, chainwheel wobbling) before you lost the bolts. Anytime a bike starts to be noisy it needs to be investigated before becoming inconvenient and expensive to repair.
