Ohh, I can see many older guys geting all very stiffly getting to their feet and here it comes......... Whwe we traimed a thread had to be cut by hand!
your the boy'os for me, A friend over here is in dire need of an 8mm bolt left hand thread, see theres the problem, (I dont have metric wheels so I am out, the harder it is the better its a kr*p saw and keeps stripping the bolts, and we all want wood for the comming [cold winter]
any one up to the job? Tug

I don't have a lathe up and running at the moment, otherwise it would be a simple job, but maybe this might solve your problem in the short term.
Seeing as it is a screw chewer, maybe you need a method of making more than one.

Dunno what the problem is with the saw - in the long run it would be better to solve this basic problem than keep replacing the screw
My first thought is to Google M8 LH threads - and Allthread do lengths of M8LH threaded rod. Buying one of these gives you potentially dozens of whatever length you need, and they can be replaced with liltte grief - but you might need a few LH nuts to make it work (get some LH washers at the same time ;D)

They also (probably) do it in zinc plated, A2 or A4 stainless, etc
If this for any reason cannot work - there are lots of fastener suppliers who sell M8LH in any length, type etc.
If you need hard - you should go for cap-head (allen head) bolts or screws
Not knowing the exact application, I can't tell if any of these are workable, but they are available and not expensive
Hope it helps

Any chance of some pictures of your work we all like to see examples of craftmanship and what we should stride for.

May the more relaxed among us simply stroll for better craftsmanship? :)

John/Andrew, Thanks for the words
I was only asked, and for the minute brain went ded, again
John I have some reversable washers one side left hand the other right hand,
cost a fortune at the time. Tug

Sorry to say but there are LH washers! SPRING and ANTIRATTLE for said LH applications.

Tug,
You probably gathered that people would like to help, and could possibly do so more if we had more info (and Pictures ;D)
Hope there are some glimmerings of the answer appearing.
Proteus - I was employing hyperbole, irony and modesty.
I was actually thinking along the lines of the definition of an engineer as "a person who can do well for a shilling what anyone can do for a pound"
If you use gas or electricity in the UK, or have landed at HK airport you have used my engineering, but I can only claim to have contributed in the team.
