Long shot says 1/8 NPT... Yossi, I lost your email did you get the Heims?

[yossi]

hi  bugpac

yes got them almost two week ago

have been in the reserve army so no computer for that time

will try 1/8 and see

thank you

[Admin]

Good deal, what is the brand of master? I am pretty confident in the 1/8 may be be able to offer a definite answer knowing the brand...

It is possible that it is a 10mm X 1.25 or a 3/8"-24 as well

Jusr grab a handfull of similar looking bolts and try them. Easy to identify.

Yah and once the threads are all bunged up.......  Then look for the instructions. 

[yossi]

 they where bought from   cip1 dot com
 there is no instraction 
a quick email and the answer is 3/8"-24   BUT have tried that and  it doesn't threads all the way in
 so i"ll just have to keep looking or i"ll re-thread it for what i have and can use and that is the end for searching

Shouldn't it be a tapered pipe type fitting, so it should not thread all of the way in........?
