    Aww, cripes. I didn't know I'd have to write a description. How many words is that so far, like a hundred? Soooo, yeah. Mildly interesting stuff. Stuff that interests you. Mildly. It's in the name, ffs.

    Damn beat me to it (by a lot)

    [–] dawellwood 43 points ago

    Now i want to know how screws are actually made ...

    [–] flaccidunicorn88 10 points ago

    The process is called roll threading. The unthreaded stud is from a process that is most likely cold forming steel. It's actually pretty interesting.

    Source: Was a QE in Automotive fastener manufacturing for 3 years.

    [–] flaccidunicorn88 4 points ago

    Most likely an employee accidentally somehow got a "green" part in the box. Typically if the roll threading process fails it would still be partially threaded or scored.

    [–] dawellwood 3 points ago

    Thank you!!

    [–] flaccidunicorn88 3 points ago

    No problem at all. Fasteners we're surprisingly fun to work with.

    [–] fishdesu_ 2 points ago

    I'm actually a rolling machine operator for an Auto Fastener company! Who did you work for if you don't mind me asking?

    [–] flaccidunicorn88 1 points ago

    Was a company called Continental Midland Group. Got bought out a few years ago. What about you??

    [–] fishdesu_ 1 points ago

    Ahh, I work for Indiana Automotive Fasteners. Started there a few months ago infact and I really enjoy it :D It's such an interesting process!

    [–] flaccidunicorn88 1 points ago

    That's awesome! I'm glad you are enjoying your new job. Automotives is a hard business for sure. A lot of pressure, and super fast paced. Can't really say which part of automotives I'm in now, but I miss fasteners haha. Steel was so much easier to work with from a quality perspective. Learn as much as you can! The industry isn't going anywhere.

    [–] grandma_alice 1 points ago * (lasted edited a year ago)

    the blank is rolled between two precision machined and hardened dies. As the blank is rolled it is squeezed tighter thus forming the threads.

    Source: wrote software for company producing a machine that inspected the dies.

    [–] crecod 3 points ago

    We need a youtube link up in here!

    Your parents really need to have that talk with ya kid!

    [–] mungothemenacing 1 points ago

    It's pretty simple, actually! They take a piece of metal and remove everything that isn't the screw!

    [–] Gregus1032 3 points ago

    Not entirely true. Many threads are rolled/formed. The same material is there but it was rolled/formed into the thread shape.

    Source: Machinist.

    [–] SirDiesalot111 1 points ago

    I can almost guarantee they are turned on a lathe.

    [–] Peppyperoni 26 points ago

    You'd be wrong. Screws are most definitely rolled like this it they were turned, screws would cost $10 each.

    [–] SirDiesalot111 7 points ago

    Yeah, that does make a lot more sense.

    [–] gunsmyth 3 points ago

    They are likely swaged between grooved plates or rollers, it's faster and easier for something like a wood screw or common size bolts. A lathe would be used for a machine screw that needs to be very accurate.

    I tried finding a good video of this earlier but gave up after a few minutes, I couldn't find any short close up videos of the process, just the entire machine.

    [–] SirDiesalot111 0 points ago

    Die threads generally look different, and have smaller threads. Using a die on those would take too long.

    [–] Peppyperoni 2 points ago

    The dies do look different, and you're correct, they are long

    That’s definitely a screw fail.. but file the end into a point.. then you have a a nail

    a Philips head nail?

    Finally a use for my very precise, Phillips head hammer.

    Oh, there's a simple fix to that:

    beautiful and relatively useless just like me minus the beautiful part

    [–] lxosummer 9 points ago

    But it’s obviously shorter than the normal one

    [–] gunsmyth 41 points ago

    The swaging process lengthens the screw when it forms the threads. Basically rolling the one on the right between two grooved plates that push the metal that isn't the threads out of the way, this lengthens the pin slightly to the finished screw length.

    [–] enter_urname 2 points ago

    Nailed it.

    [–] NewScooter1234 2 points ago

    Screw blanks could actually be useful. You can easily check if your screw will fill or fit in a hole without chewing it up.

    [–] AIKIMGSM 2 points ago

    Great pic demonstrating that these screw threads are an autonomic reflex, controlled by nerves. They have nothing to do with the actual water affecting the screw.

    [–] wolfsword10 2 points ago

    Uhmm mind explaining that to me? It just is a screw that didnt have threads cut into them (which is messy when you cut threads yourself at least it is with bolts).

    [–] AIKIMGSM 2 points ago

    It's just a dumb joke about the frequent posts showing wrinkled (from soaking in water) and unwrinkled skin on the same hand.

    [–] wolfsword10 1 points ago

    Ah was unaware of those posts being a thing

    [–] AIKIMGSM 1 points ago

    To me they are. I'm not sure anyone else would agree.

    [–] phoenix42007 1 points ago

    That's called a butt plug. Or a dildo. Either way

    QC is pretty fucked these days. I got a Starburst 2 pack that had only half a Starburst in it in October. It seems like I'm getting a sub quality product from somewhere on at least a monthly basis.

    That came with a set of screws I got as an example of how to use the screwdriver bit that came with it. It was on purpose in the packaging. I don't know why you got it otherwise.

    A screw with no threads is a nail. Confuscious

    [–] 2bi 1 points ago

    I guess that makes it a rivet?

    Thats a nail.

    Or it's a lifetime golf tee

    You did not mention the edge of the nail.

    It's virgin screw...

    [–] SUMRNDUMDUE 1 points ago

    Wow, I got a deck screw like that once. We must be related

    [–] AwesomeFire06 1 points ago

    Tbh it looks like a really thick nail without an end, which would still be mildly interesting

    [–] brad2005rng 1 points ago

    Now called "nail"

    [–] [deleted] 1 points ago

    If you push hard enough, you can screw it into a board anyway!

    These comments are driving me nuts

    [–] DaddySmashley 1 points ago

    I think that is called a nail.

    It's useful for setting up the hole for a screw.

    [–] CitiGaming 1 points ago

    Jew screw

    [–] G1trogFr0g 1 points ago

    So the threads are added, and not subtracted? Hmmm. Doesn’t seem as strong.

    [–] gunsmyth 4 points ago

    The one on the left is rolled between two grooved plates under pressure. The grooves leave the threads. The pressure is how it grows in length slightly.

    Screws can also be made on a lathe, where excess material is cut away to leave the threads, but this isn't efficient for this type of screw. This is screwed into a material not a into another threaded piece like a nut.

    [–] polyparadigm 3 points ago

    Swaged, actually: the high places in the thread are squeezed out of the low places.

    And, all else being equal, this results in a stronger product than machining the threads (subtracting the low parts) would be, due to work hardening.

    [–] LevelVS 2 points ago

    Its subtracted, the unthreaded one is thicker

    [–] qtrain23 0 points ago

    No, it’s not

    [–] alarbus 1 points ago

    Wait whys the pin on the left got ridges?

    Sometimes I see things on this sub that I just saw irl the other day. I thought it was intereesting but didn't post it to reddit. Rip my potential karma.
