LH Thread Bolts
What are my chances of getting a LH Threaded bolt. I haven't confirmed it but I'm guessing it is a ⅝ UNF.
I was wondering why I was having so much trouble undoing the darn thing. The centre part of the thread is all worn away where the machine has a pivot on it.…..Live a Quiet Life & Work with your Hands

Have to have a working lathe to do that……I also have never turned a thread, wouldn't know where to start. I'd like an easy fix on this one so I can get a project finished for a change, rather than wait for another machine to be finished before I can use it to finish another. I'm alway chasing my tail that way, going in circles.…..Live a Quiet Life & Work with your Hands

You might be lucky at one of the big fastener places. Phone and see. I got a 1/2" LH whit. nut there once.

How long.... I would imagine a standard 5/8 left hand bolt not that hard to get.... years ago I had no trouble getting left hand nuts..
Light red, the colour of choice for the discerning man.

If all else fails one of these might help. http://www.ebay.com.au/itm/L-H-UNF-5...item19c060cd4b
Like others have suggested, I would try the big fastener places first. In Tasmania Nuts and Bolts P/L are excellent, and they have some interstate stores too, but I don't know how extensive their network is. There are others, Coventry Fasteners being one and their minimum charge possible won't be a problem in your case, but check your local guys and maybe ring your nearest Nuts and Bolts store if postage won't completely blow your budget. I have no affiliation with Nuts & Bolts other than being a happy and satisfied customer, ditto LPL above.

DSEL can you measure the length you need, thread and pitch and type (60deg or 55deg) and confirm what it is? I'll have a look for you at the local threading places. They have quite a few sizes.
The other thing you may not have considered is that you can get Allthread in LH in some sizes. Nuts are not generally a prolem at all.Cheers,
Joe

The whitworth thread gauge don't have anything I saw as close.
Here is a photo with the tap.
As you can see it has a similar RH part.

Hi Dale
If all else fails ring Keables. They were in A'Becket St in the city last time I used them.
They have a HUGE range of stuff IN stock

I did try Keables and fyi they have moved to west footscray. The said they only Cary lh nuts, never ever stocked bolts. According to them lh bolts are all custom made. I have tried a number of stores nine carry lh bolts either. They are used in production machines so finding a matching one as a spare part would be a needle in a hay stack.

Our local speciality store has some LHT all-thread rod in various sizes which I have used to make LHT bolts - unfortunately it's all metric.
