Well, yeah, there are a number of variables here:

*Lets say that the hole is 10mm and the thickness of the wire is 11mm then it is safe to assume that the answer is: zero

* But now lets take the same 10mm hole and here we have a coiled wire, much like a spring that when compressed is 11mm... At first glance you say, "No way" but when you stretch the coil (spring) with every 5mm you stretch it the diameter in decreased by 2mm... With me so far??? So if you continue to stretch the coiled (round) wire three fold over it's coiled diameter it will no pass thru the 10mm hole endlessly, or the length of the round/coiled wire...

No???
