Threading die vertical handle?

[Jake M]

I have no idea how to word this.
I need to chase some threads on a stud to clean them up after sitting in the rain for a year. They're not actually rusted but a nut won't run smooth on them.
They're a size that's not mainstream so I bought the die I needed. The problem is the typical die holders have a very wide span and, without removing the studs (Seriously locked into the aluminum manifold) I only have a couple of inches to work with.

Is there a tool that holds a threading die vertically?
I think, either way, I will end up making one.

A thread chaser might be the best answer, versus a thread die.

Hex dies are almost (not quite) universally "built" to chase damaged threads, versus cutting brand new ones.

Either of those options drives with a socket set if you want.

Round dies are "most often" made to cut new threads. Be awful careful to get 'em started dead straight if you're reparing/chasing threads, as they're gonna go where you send 'em regardless of where you want them to go...

For just chasing? You've gotta get a round pipe, hollow bar, something of that nature, bore one end to just fit the die, and tap a hole for a set screw which might need a custom tip, to catch one of the drive features. The back end could have an old, duplicate, or broken socket welded or pressed in (won't see huge forces), or you can just cross drill it and use a socket extension as a handle...

Or there's multiple names for this, but you can peruse the internet for "hexagon round die holder". Those take big sockets, but they drive with sockets...

Or in the worst case scenario, a little wire wheel on a dremel tool can do wonders in a situation like that where it's "patina" and "gunk" moreso than it is displaced/damaged metal.

Cut a slot in a nut and drive it on with a socket.
