Earth rod driving stud size

[Mike Johnson]

Can anyone tell me the socket size of the head to a 5/8" Earth driving stud, the bolt that fits into the threaded joiner?

I’d imagine 16 mm

I'm a hundred plus miles away from mine so trying to visualise.... bigger than you'd think, I'd say in the 24-28mm area comfortably

25mm according to screwfix Q&A

Hi - I have that Screwfix version and can confirm it’s 25mm, at least at first. I use their brass joiner to couple down onto the rod top and have at it.

I am also a few hundred miles away from my workshop, hence the question, thanks for your input guys, I think this is what I need: https://www.ebay.co.uk/itm/Kennedy-...a=1&pg=2060778&_trksid=p2060778.c100290.m3507

Measuring the one I have gives 25.86m

So you need a 26mm af socket.

Just tried a 25mm socket, and it won't go on, but 26 does.

Thanks Julie, looks like the socket I linked to above will work @ 1-1/16 = 0.269875

I was close then ??‍??‍
I meant the thread size ??‍

1.0181"

Is that any better?

5/8" UNF would be 23.81mm
M16 would be 24mm
5/8" BSF would be 25.65mm
So it seems it harks back to Joseph Whitworth days!

The higher quality rods are threaded to UNC-2A ,and that would be an imperial 1 1/8" A/F,but as they are not made as a fastener,they can use any combination of size/type.

A 26mm socket is included in larger sets.to pickup imperial sizes,between the standard metric increments.

one size fits all:

Why not just use an adjustable spanner. It's just one bolt.
