Not uncommon to find weird hex sizing on older NZ products. They used whatever they could source.
Either an adjustable spanner or a disc grinder is called for...

They ALL sell them. Check it out yourself ... or look through a few second hand shops. (Op shops)
Most engineering supplies type shops will have them ... no big deal really ...

I was reading about Mr Whitworth recently quite interesting.

Napoleon was a sneaky bastard - he lost but left the metric system behind him.
I grew up thinking in inches etc - then had to change to metric for most things. But I still work to less than a thou tolerance building engines.
No idea what that is in metric...

I just remember .040 to the mm, that makes ten thou quarter of a mm & work in or out from there, add & subtract zero's as required.
Works in my head anyway.

They taught us that antiquated shit at school, I still use it sometimes or relate the measurements between the two

1 thou = 0.0254 mm

Ok, that makes my method out by 0.0004 of a mm:crazy:

yes i remember 1 in= 25.4mm
For some reason the only fuel consumption figures that make sense are miles per imp gallon.L per 100 k is starting to take over there.Peoples heght is still feet and inches to me.

Mitre 10 have some items they sell individually ... They might order it in for you ...
There used to be a firm called Gas and Engineering Supplies (GAS) they changed name (and I can't remember what is the new name) ... they sold such like in the singular ...

Try playing with Jeeps.... Some nuts are imperial, others are metric. And to top it off, bolts are a mix of metric, imperial and torx! I have ended up with three tool sets.
Mitre10 has better selection than Bunnings. Repco and Supercheap Auto will both have imperial sockets.

Mitre 10 (especially the Mega versions) usually have single sockets - in fact there was a discussion here about it because someone needed 28 and 30mm sockets and wanted low entry ramps on them because their wheelnut was only 6mm high.... they ended up using Bahco ones from Mitre 10.
I had a look when I was in there for something else and they look good. I really rate Bahco stuff - I've got socket sets and files and saws which are really good value for money I reckon.

having maintained old British cars and bikes, German built bikes and Japanese bikes, I have three rows of ring spanners on my shed wall - AF, Witworth and Metric - a spanner for every occasion ..
I like to throw them into the works ..

Bunnings, Mitre 10, Super Cheap, Repco - I've sourced spanners and sockets wherever I can ..

I bought a bucket motor (The Rat) from Ken Steadman and it had at least one example of every type of thread known to man. Not one bolt head was the same as another.

was ken in the airforce too lik ejimmy, they were probably vey expensive bolts. remember him racing the ohakea gp on a g4tr kawi, in a dinner suit with saddlebags, he won but it looked real funny, were gret meets on the little base roads, matched the bikes real well

Dunno about any of that but it did come with a Holden HQ heater core for a radiator.
