You could just use a M12 threaded rod available from many DIY stores ... e.g B&Q.

I bought the bars and even a converter from Aliexpress.

Assuming that bar is 8mm, which it probably is then yes it will work. That is the exact same adapter I bought for my counterweight bar but I am not familiar with the specs of your bar.

Thank you Astrodave.  It's hard finding any information on line regarding this counter weight bar tread size from the Celestron astromaster 130 eq on the internet. I'm assuming it is M8 and I figure the M8 to M12 adapter will be my first attempt to use what I already have at a small price.  I was just hoping to get someone to verify this bar is M8.

Hi Everyone, it looks like I will be converting to EQ mode for my AZ-GTi mount but I have a counterweight bar question.  I read that the AZ-GTi needs a counter weight bar with a 12M Male Thread.  I have a Celestron Astromaster 130eq counter weight bar that is to smaller and I'm unable to find the correct thread info for this bar.  Does anyone know what the male thread size is?  Is it a standard 8M?  Would this M8 to M12 adapter work?
