  • I need some nuts

    This circuit breaker was missing from the Servo 150 that came on my new to me mill, so I ordered it from an on line supplier.

    To my surprise, when I opened the package yesterday, there were no panel mounting nuts included. Went to the supplier's chat room and the tech tells me the nuts should have been included, and says to contact customer service. The nice CS lady says she will contact the warehouse about the missing parts, and will send them out asap. Last night I get an email saying they looked at their stock and none of the items have nuts in their boxes. They are checking with the product manager, but have not received a response as yet. Please let us know how you would like us to proceed if we should continue to research regarding the mounting nuts or not.
    Duh! OK, so figuring that this was going to happen, I spent most of the afternoon on line looking for 1/2-32 panel nuts which apparently are an odd size. Also made stops at a couple local hardware stores, and as a last resort, Home Depot. No luck anywhere. One hardware store came close with one at 7/16-32 that even had a rubber boot over the bat handle. So my question is: Does anyone know where to get these nuts without having to buy them by the pound? It's beginning to look like I'm going to have to make them and not looking forward to turning a 1/2-32 internal thread.

    What is the big deal with cutting the thread ?
    Don't know, time to learn.
    Easy with the right machine..

    Shallow threads are easy to cut , but tool must be sharp. Make several blanks in case you flub one.
    I would Knurl outside of 5/8 aluminum or plastic.

      1/2-32 would be easy to single point on lathe.
      Not too small to work on but small enough that you don't need to take heavy cut and your boring bar can be still plenty of thick&stiff.

        I have a bunch of switches that I call 1/2", but measure 0.456 - 0.464. What does your switch measure?

        I just checked DigiKey for toggle switches and one of the sizes is 15/32 x 32. Which must be what mine are. Those nuts are commonly available.

          Manufacturer has them in stock but they say 39 week lead time.

          https://www.digikey.com/products/en/...nut%201%2F2-32


          No lead time given here, but you can call.

          200 in stock here:

          Dead easy internet search. Less than 5 minutes and three sources. Grayhill should be able to tell you who stocks them. Just call them.

            I have had to make some similarly fine threaded nuts recently. I grabbed a broken tap and ground away all except the first good tooth. It made a great threading tool. Perfect form and much easier than trying to make one from scratch.
            It's all mind over matter.
            If you don't mind, it don't matter.

              I'm pretty sure I should have some of those kicking around. If I do I can put them in an envelope. Send me a PM and I'll check tomorrow when I have a moment (going to what Avengers with the fam in 10min).

                You really don't need a 1/2-32. Any old tap with 32tpi will work.

                      Some folks will go to a lot of work to avoid grinding a 60 degree cutter.

                          Do yourself a favor and use the version that protects the breaker lever. Or make one... I've replaced way too many busted off levers on the servos. The supplier I use supplies the protection version.

                            Dave, in the lamp accessories area of homey depot there should be some hollow threaded rod and nuts that are used to repair or install wall mount light fixtures. I believe they are the same thread. Jim
