It looks as though they are not nylock or lock nuts so its is possible they are 1/2" bolts.

If one of those bolts goes in 3/4 of the way in, it's more than likely the correct one. If its the wrong thread, it will stop at the 1st or 2nd thread and won't go in further. Does it go in that far using finger pressure, or do u need to use a spanner or socket to get it in?
Goes in that far with finger pressure but it stops in exactly the same spot for all six nuts.

Hmmm, bizarre. Does ARB Use unique bolt sizes that are only available from them?
Nah I dont reckon. I'll try the 1/2" unc next

Hello from Under Down Under!
Might be BSW thread , only reason aftermarket use imperial is cost, 1/2UNC x 2" could be 40 cents
where as a 12mm 1.25 pitch x 50 are $1.07 each. I know cause I buy by the box all the time.
I'll ring my bolt place this morning for you and see what they think.

bumped. @ Lucas, rang my bolt place and came up with this , Its like I said more than likely its BSW, thread which is 12 TPI [teeth per inch] instead of 1/2" UNC which is 13 TPI.
One interesting point he made was that BSW bolts don't come in HI tensile. I'd buy a 1/2" UNC tap and re tap it so H/T bolts can be used

A quick search on google found someone using m12 1.25 thread pitch.
@ Parksy thats metric fine, my money is on 1/2" BSW.
a lot of after market trade use BSW and in weird sizes like 9/16th bsw
I'd either one re tap it or cut nut off and use correct thread pitch.
Just saw pic cutting nut off not an option, run 1/2 unc tap through it. done

Think it would have been easier for you to drive to your parent's place Lucas!
