Bolt Threads on Chassis?

There are a handful of threads along the chassis rails. Anyone know what size and pitch they are? I'm looking at securing an air pipe along the rail to the tow bar.

Just run it thru the centre of chassis rail if you can.
Quicker and easier plus offers stone protection.

I did mine that way.
Can be fiddly getting it over the rear diff area x tube but it's doable.

I used 1/2" truck air line. Easy push fit connectors.

I thought about that but I'd much prefer to run it along the side of the chassis rail for a number of reasons, hence asking about the threads.

When i fitted my TJM side steps i used a standard M8x1.25 tap to clen the treads out.
