SME V - VTA screw replacement

Does anybody know where I can buy a replacement vta screw other than going thru some Sumiko dealer? I bought a V but it didn't come with set up tools. I've been told a hex screw would work but I don't think that is the case, it seems like I would strip the threads.

Thanks in advance for any help.

It is a weird "Witworth" size you can't get just anywhere.
There you go.

Thank you for that info, never have heard of the BSW thread pattern.  Seems like the SME VTA Screw is 1/8" BSW, looked for Screws which seem very hard to find especially in the length required, However a Die can be bought for GBP 5 http://www.tapdie.com/html/bsw-_dies.html
so one could easily make one from a piece of Stainless Rod or similar.

I do not think it is a 1/8BSW, because the original VTA Screw has 2,7mm diameter.

The Witworth does seem to be a very odd choice although it does have that empire esk heritage.
