A dummy shaft like this is a service aid: it's a stand-in for the actual axle or stub axle, letting you support the wheel and bearings correctly while the real axle or hub components are off the bike for work. It's a tool-like part rather than something that stays fitted during normal operation.
The manufacturer tag on this one says Norton, and a related catalog listing calls out an axle/stub axle for a Mark III rear wheel, which lines up with a Norton-family disc rear end rather than anything Triumph. If you're trying to match this to your bike, give us a call and we'll confirm before you order.
