Spotting Scope Thumb Screw

#1

Post by KingNothing13 »


Can anyone here help with this question...

On my Apertura, one of the tumbscrews for the spotting scope broke at some point, I am looking to replace it, but I have no idea what size thumb screw to get.

I know it is a "nylon thumb screw" the fastener portion of it is 1/2". Does anyone here, that also has the Apetura (I assume this spotting scope was similar across all sizes), and a better knowledge of how fastener sizes work have an idea of which screws I should purchase?

Thanks!

Brett, the finder on these scopes is a standard GSO 8x50 RACI.

You can email Jim at Scopestuff to verify (he also sells these RACI's) but I believe the 8-32 is the one you need.
