What kind of bolt is this?
(OP)
You can see the attached poorly drawn sketch, but I am looking for something kind of like a shoulder bolt but the shoulder part is a lot bigger than the bolt part. (Something in the neighborhood of a 1" shoulder to a 0.25" threaded)
This is not going to see any load it is a target for a prox sensor to pick up on. I am just wondering if this is something that I can easily buy rather than trying to get it made. Thanks

It was kind of a shot in the dark to see if anyone had com across something like that and knew what it was called. Thanks for the input.

If you absolutely have to have an internal hex drive you could have made by EDM,

I don't believe it has a name as you essentially have a stripper bolt with no head and small thread end. There are dowel pins that have internal threads, but no drive end.
Is there any quanity involved?

As this is what you describe as a 'flag' for a proximity sensor, I would suggest that you have it made from bar stock of suitabel material.
The most complicated machining seems to be the mechanical grip for the 'screwdriver' or wrench (whatever).
As a proximity flag the application surroundings could perhaps indicate the wish of a simple, smooth-faced surface and as simple mounting/demounting as possible.
You could perhaps evaluate reforming the grip/slot for fastening to to a diagonal bore, later plastic-capped, or the device made totally from hexagonal bolt, or square machined top or bottom for wrench?

This is not an off the shelf part. Now, the above statement from unclesyd is correct provided you have to have hardened material, you cannot drill/broach a hardend part. From your description of the application not being load bearing, go with a low carbon steel that can be easily machined (1018, 12L14) and broached (for internal hex). Sinker EDM is a longer process = more expensive.

Do you have a machine shop at work they could make you a few for spares.
