Nobody understands the size because the language and terminology you are using to describe it is vague, open to misinterpretation and non-standard.
It is said that a picture paints a thousand words. Take or find a picture of the item with which the spring is used and then we might understand what you want.

Well, with respect, as member ChaiLatte already pointed out (above), you haven't given us enough info.
Does this spring have to fit "snugly" on the OD of the bolt? Or just "loosely"? Does the spring fit into the bolt hole and exert some upward tension on the bolt? You've already said "into a 3mm bolt hole": What does that mean exactly/what job is the spring doing?
Sorry, but I'm sure that for you, with the equipment (or whatever it is) in front of you, it all seems quite obvious. But for me at least, I can image at least 2 or 3 different scenarios from the minimal description in your OP, and they'd all likely be wrong!
A picture (with a phone camera will do) or even just a rough sketch will help stop a LOT of guess work. Even better, what about a photo of the "complete equipment" showing where this 3mm bolt goes, what it does, and what that spring you want is supposed to do.
P.S. My post crossed with "CL's". He's said it better than I did. Just tell us what the machine is that the spring comes from. That'd be a good start.

A bit like a ballpoint pen
3mm diameter, 10mm long, 0.2mm wire diameter:

Springmasters, as already mentioned, have many options close to these dimensions.
There is also Lee Springs, who have a vast range of stock springs.

Loads on EBay…with size options.various lengths diameters and wire diameter…usually from China….make take a while, but very cheap
Cannot you find one on something else like you’ve suggested…a ball point pen and cut to length

There is a big difference between typing 'loads on eBay' and providing a link to a specific item that is sub-3mm diameter and 10mm long, which is what the OP seeks.
If he needs 100pieces, that is a lot of pens he has to liberate from the office stationery cupboard. Maybe he could smuggle them out in his socks, 20 at a time.
