Celestron AVX RA Axis:  What size is the allen wrench for the set screws that hold the RA axis collar ?   I have tried each millimeter size from 1.5mm, 2mm, 2.5mm and nothing fits properly..    Thanks in advance.

The AVX is an EQ5-class mount.  The RA aluminium lock-nut of my LX70, which is also an EQ5-class mount...

Both mounts were manufactured by Synta.  I used either a 1.5mm or 2mm.  Try again.

Thanks for the wrench info, 1.5mm …. seems the set screws are stripped but I was able to slip the collar enough to complete the free play adjustment.  Sometime in the future I will drill the set screws  out to replace them.    By the way SUPERLUBE eliminated worm gear chatter , hooray !!!!
