Hey there

For various DIY projects I have in mind I want to design/create my own SCT adapters and etc.
To start with I have very very limited experience in CAD software, but I'm trying to learn...
So far I was able to learn how to do it in Fusion 360, but what I miss are the specs of the thread (at least). All I could find online is that it is 2", 24 TPI which tells me it is 2 inches wide and has 24 threads per inch. Nothing about the internal or external diameter.
I can tinker around the following variables below. These values are mine and nowhere near the real-life sizes. The only correct one I believe is the TPI value. And I guess they should be different for male and female threads.

Code:
    <Size>2</Size>
    <Designation>
      <ThreadDesignation>1-24</ThreadDesignation>
      <CTD>1-24</CTD>
      <TPI>24.0</TPI>
      <Thread>
        <Gender>internal</Gender>
        <Class>2B</Class>
        <MajorDia>2.072</MajorDia>
        <PitchDia>2.0598</PitchDia>
        <MinorDia>2.0475</MinorDia>
Can someone knowledgeable shed some light here and help me fill the gaps?
