  • No, we were all talking about how they use screws of different pitches, as standard pitches vary with diameter, when they could and arguably should use screws of matched pitches. Some moron read my comment on that last bit as a complaint about variations within a batch of screws of a specific pitch, and other morons ran with it.

    If you believe I missed the point that screws of the same pitch, regardless of diameter, would move nuts axially(not just “vertically”, but in the orientation of the screw itself) the same distance with the same turn incriments, then you have no idea what I was saying or can’t be bothered to actually read it.

    Imagine me, machining screws on a lathe, as I do, without understanding that its the consistency of the feed screw(or die if using that method) on my lathe that makes it possible. Or that I could switch my SAE feed screw with a metric one to make producing metric screws easier. Or that I could add a 127/100tooth change gear into the mix instead.

    Right, I’m the ignorant one here. Machine Fabrication … its literally in my username, but no, misunderstanding/misreading my comments and throwing garbled versions of them at me because others have done so is more important than understanding the topic at hand.



  • Those agencies are under the executive branch, and its been made very clear in the past that they prefer sneaking in backdoors to valid best practices.

    The NSA sabotaging the Elliptic Curve method of random number generation used in the RSA algorithm comes to mind. They would otherwise be THE experts to trust, but lets look at the others:

    FBI - Waco, Ruby Ridge, planned to assassinate Martin Luther King and so many others. CIA - promotes fascism internationally, causing all sorts of chaos in Latin America and the Middle East. Ever wonder how Komeni’s faction overthrew the Shah? The CIA decided he had gone soft.

    Germany is so trusting of the US on cyber-security measures that their government has been trying to ditch Windows for over a decade.

    TL;DR: In the US, government experts do NOT have your personal security best interests at heart. They can and will use any dirty trick possible to spy on and control both our own citizens and those of other countries. Last authories that anyone should trust.

  • Even in millimeters, there’s a wide range in standard thread pitches. 1mm thread pitch in most common screw sizes is generally available, sure, but don’t always fit the “cheapest sufficient part” criteria.

    EDIT: Dudes, the standard pitches between various sizes of metric screws does vary. This isn’t in reference to variations within a batch or whatever other garbage take 4 people apparently came up with, its just a fact.

    versus:

    Good lord, I could machine you a set on my lathe, easilly, but its not necessary. Just get you a tap & die:

    Where am I getting the idea that these manufacturers don’t think like this and just buy the cheapest crap they can find readilly available? My siblings in christ(or whatever), how do you think we came to be on this subject? Machines are getting put out with components where the pitches are all over the place in locations where it would make more sense to match them up.
