"116" may be the overall length of the old axle, but unlike cartridges bare axles are often asymmetrical. Measure the distance from each race to the end.
Two notes on 113 v. 116:
1) Quoted (symmetrical) axle length is to achieve a standard chainline. The actual front chainline needed is determined primarily by the rear chainline. If that's non-standard then the crank OEM's recommendation needs adjustment.
2) Chainwheel position can be limited by the chainstay, as you noted. But a fat stay is far from the only reason for it to run into the (optimally positioned) chainwheel. Some bikes have flared stays to clear fat tires. That's why mountain bikes (fat tires and maybe suspension) now have a different "standard" chainline than road bikes (skinny tires and human suspension).
