Can someone tell me the size of the adjustment screws are on a EQ5 Polar scope I want to replace them with thumb screws please.

I think they are M3-10mm

Thankyou.

I used these ones: Ebay thumb screws

May have had to file them down very slightly to get the dust cap to fit.

Brilliant thanks Just looked on ebay nearly exactly same ones you posted £3.69 computer case screws. These are M3 10mm will they be too long would the 8mm be better.

The 8mm ones definitely gave enough clearance, but the 10mm would probably be OK, too.  

If not, a few minutes with a file should sort any clearance problems.

I did try some larger thumb wheel type ones (because they were sitting around spare in the bits jar) and these fouled the dust cap, but the small headed ones were fine.

Thank you very much I will send for these now.
