You would be using the aluminum fork legs threads to do the job of the steel stud when removing the wheel. After repeated removal it may become loose. Where as the steel stud if replaced would not become loose in the fork leg.

The dealer should have the studs. 6 x 1.0 ?

 

I see what you mean now. I got the broken stud out with some PB Blast and my good linesman pliers and a lot of strength. Now to just find a stud, too bad nobodys gonna be open to get one til tuesday.

 

The bolt idea is fine for temporary use.

 

The reason it's a stud is that the front wheel has to be removed quite a lot over a bikes life, and a stud ensures that there is not a constant use of a relatively soft thread.

If you have the old one already out, then pinch 2 nuts together at the end of the new stud and wind it in until it's in all the way. Torqueing is not required as the pressure on the stud is pulling out. In fact do not put any more pressure on the stud than is required to screw it in. It's of no use and any more pressure risks the thread in the fork and then you have a problem

A bolt will work but each time you have to use it you will risk the fork.

 

Wind in a new bolt, then cut off the head with your Dremmel.
1 new stud. The bolt will be metric. You could use one from your bike if you've removed some of the surplus parts.

 

Not a bad idea.
A stud usually has a smooth centre bit but for this use, it would be fine.
Just don't over tighten it into the fork. Just firm.
And don't screw it in and out, in and out getting it right.
Choose what ever you are going to use and screw it carefully into the fork once.
it is very easy to ruin the soft thread.
I don't mean to labour the point but,

Oh, and btw, the stud length is 35mm.
