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.

I would contact SME directly. I did when in the same situation a few years back, the screw was expensive about $ 50 or so when all postage etc was figured in.

Good luck

Here is the link to SME
http://www.sme.ltd.uk/content/Spare-parts--Accessories-1310.shtml

Email them for price and shipping.
I'll suggest contacting Sumiko directly (rather than a dealer): 510-843-4500. They were quite helpful to my parts inquiries and do keep stock on hand.
Yup, I ordered one thru a local dealer and got it within a few weeks. You can set the VTA without it. Just loosen the clamp screws and you can move the arm up and down by hand, Just like many other arms. It would work to get you started if you want to set it up before getting the part. BTW, I'd buy an extra allen wrench from them that adjusts the height of the armrest. It is a weird "Witworth" size you can't get just anywhere. I misplace mine and couldn't get the armrest out of the way for a couple of weeks!
Thanks for the responses! I called Sumiko and they didn't have any in stock but suggested smetonearms.com (closed for good Friday) and flatearthaudio.com (didn't answer). Thanks for the help though. I'll try again next week.
I've dealt with Flat Earth and Teresa was great.
Just fabricated one for myself. Works great and makes fine adjustments for VTA and rake angle easy. Had to buy parts enough to make 3, so if you want, I'll make one for you and send it for $25 postage and all.
Thanks a ton for the offer but another member just happened to have an extra one and sent it to me. Sorry I didn't update.
Can anyone tell me the diameter of the thread? I think 2,5mm?
It is not 2.5MM nor 3MM so must be more exotic.


Best of Luck

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.

Good Listening

I do not think it is a 1/8BSW, because the original VTA Screw has 2,7mm diameter.
It is maybe an #4 - 48UNF

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


Done a little more research the thread size is 6BA 

https://en.wikipedia.org/wiki/British_Association_screw_threads

Correlates with the apx 2.7mm thickness and the 48 threads per inch

Found some all thread on eBay but the seller in England will not ship to the US

Don't know if above will ship to the US but it might be worth a try

Best of Luck
