still need bunches of 1/4-40 nuts

  1. We are crucially short of this item used to mount many of our eBay
    offerings.

    No, this is not a misprint. 1/4-40 is an ultrafine nut used on submini
    switches and miniature phone jacks.

    Pricing goal is two cents each in lots of 5000 to 50,000.

    try
    http://www.mcmaster.com/

    for a bulk quote. IIRC they are about $0.20 per in 10 quantities.
     
  3. A quick search for "1/4-40 Nut" on www.dogpile.com, and the search dog dug
    up this bone:

    No idea of price, but 50k quantity should perk up their ears. Otherwise,
    what about the manufacturers of the switches, phone jacks, and perhaps 1/4"
    shaft pots. Also, analog meters have extra fine nuts, although they might
    be 1/4-36.

    Another bone to chew on is: http://www.cornellind.com/hbn.htm

  4. Already checked apem.
    Outrageous pricing.

    awaiting pricing on others.
    half of them do not respond; others are totally out of line.

    Thanks for your help.

    It's probably a safe bet that most of the ones who don't respond probably also
    can't come close to your desired pricing. :)

    Good luck on finding what you want at an acceptable price!
     

  6. Have you tried a company called ABABA?

    Have you not tried an engineering supplier ? The type that stock good old
    fashioned nuts and bolts ?

  8. Sure.

    McMaster Carr has them for twenty cents each and refuses to discount in
    any quntity.

    Are they the only people in the USA who sell nuts ? Are you seriously trying to
    tell me they don't offer discounts on a $10,000 order ?

    Anyway for that money you could import from China at save about $9000 probably !
    Email McMaster Carr's chief exec to explain they're exporting jobs btw.

  10. Did you not even read his post? It is not a standard "nut and bolt"
    item.
     
  11. They are notorious for being profit hungry. Their low qty price as well
    as their inability to have any price breaks for quantity purchases prove
    that.

    You need to stop being such a know nothing nerd. Not everything in the
    world fit your DonkTard "reality".
    He doesn't care. It's like asking 7 eleven to drop their prices, or
    Sears.

    They have high stickers and only care about the sales they do make.
    That's why WalMart has been beating Sears' ass.

    It is about attitude.

    They don't understand that WalMart makes more due to shear volume.

    Try your local Ace or True Value hardware store. I went to Ace and
    told them I wanted a bunch of boxes of SS screws. They ordered them
    for me at a pretty good price - this was a few years ago though...

  14. Was Sandy Yen over at Taiway Switch in Taiwan not able to help you?

  15. Have you tried getting a quote from a local turning/precision
    workshop?


    I used to get 4-40 Dtype stand offs made by this little UK firm
    http://www.colpa.net/default.htm
    Surely there must be a small venture near you that could do it?

  16. Local hardware is pretty much limited to 1/4-20 and rarely 1/4-28.

    Zero hardware store demand for 1/4-40.

  17. From previous experience, cost would be $45 each.

    1/4 inch dia thread by xx threads per inch ?

    Dear Don,

    since you're a great one for giving advice may I suggest in return that you're
    unlikely to find such stuff in the local hardware store. It's rather more likely
    you need a company trading from an industrial park/estate.

    Graham

    For 1 or a thousand most likely. It'll all be setup cost.

    I wouldn't be at all surprised if you could buy the complete mini-jack including
    panel nut from China for less than the 20c the US supplier wants for the nuts alone.

    Just throw away the sockets and keep the nuts !
