Collimation screws for Revelation 300 Dob?

[szymon]

Does anyone happen to know the thread on the Collimation screws for a revelation 300 Dobsonian?  I'd like to replace the screws with thumbscrews, I was thinking something like these:

https://www.wdsltd.co.uk/product/3200/hand-screw-metric-wds-102

(Yes I know I could buy Bob's Knobs but they seem a lot of money for basic thumb screws).

Im not sure if there is a metric versus imperial difference between chinese manufacturers and american manufacturers .... itnwill be interesting to hear what others recommend.

Cheers

synta/orion uses metric and for secondary mirror colimation screws you need: M4 x 30mm thumbscrews.

I can assume that revelation will be the same as I really doubt that they will walk away from the same thing.At the end of a day they are all sort of the same copied over dobs
