Astronigel Posted July 19, 2018 Share Posted July 19, 2018 Hello, anyone know where I could buy imperial sized nuts/bolts? Quite small at 1/16" (I think). All I've found in UK is metric. Link to comment Share on other sites More sharing options...
+Graham Posted July 19, 2018 Share Posted July 19, 2018 Just to say it is a 1/16 is not enough. There are at least 6 different imperial threads. If it is only 1/16 it will probably be a BA thread. Most of the old electrical stuff used BA threads. If you get stuck let me know. Link to comment Share on other sites More sharing options...
Astronigel Posted July 20, 2018 Author Share Posted July 20, 2018 Thanks for reply. Yes I know I need to also get right thread. I only have a plastic ruler to measure with so I can't be all that accurate. Previously I counted about 50 odd threads in millimeters to try get the size.. And with same inaccurate ruler tried get size/diameter of the nut itself.. Major mistake was thinking it was metric of course, ordered some and of course they are a little too small.. Looking again I thought they look more like about 1/16" . I didn't think of metric at all at first ..silly me.. Its for a secondary mirror holder.. Its made from 3 threaded bars...

Doc Posted July 21, 2018 Share Posted July 21, 2018 Would it be possible to take the secondary off and bring it round to me, I live in Nottingham. I have a variety of metric, BSF, UNF, BSP, BA taps so I'm sure we can find the thread size. If not maybe we can re tap the secondary to a larger metric size.
