Conductive Thread Bobbin - 30ft (Stainless Steel)

This is 30 feet of conductive thread spun from stainless steel fiber and wound on a plastic bobbin. Use it to sew up all of your e-textile projects. This small bobbin is a great way to get into wearable electronics without the upfront cost of buying an entire spool of thread. 30 feet of thread is enough to get a simple design stitched onto your shirt, backpack or hat.

What sets this thread apart from the other conductive thread that we carry is the fact that it's actually spun from this stainless steel fiber and doesn't have a nylon core. This means that while it may not be easy to solder to, because it's stainless, it also won't burn up when you touch it with a soldering iron. Suitable for hand or machine sewing (as a bobbin thread), it's particularly 'toothy', which means that it grabs tight to your fabric- if you've had problems with slippery conductive thread that won't lay flat or knot, this thread will be a welcome relief. We've had no trouble using it for close, tight connections, but if you're worried, waxing the thread should keep it manageable!

  • Made from Stainless Steel Fibers
  • Resistance: 28 Ohms/Ft

    Could a strand of this thread be used to make an air-flow sensor? This Elektor project uses filament from an incandescent bulb, but maybe this thread could work?

  • Member #448176 / about 8 years ago / 1

    Does anyone know the current rating of this thread in amps?

  • Is this the 2ply or 4ply thread?

    I am looking to integrate the heating pads into clothing. Could this safely carry 5-9 volts?

  • UrielGuy / about 12 years ago / 2

    Hey. I was wondering, how consistent is the resistance? Can I use it to measure distance? or the length of the thread? Also, Can you specify some of the mechanical properties of the thread? Breaking load i what interests me the most.

    This bobbin did NOT have 60 feet of thread. It was more like 30 feet. Half-way through a project I ran out :( - a Larger spool would definitely be helpful.

    I'm planning to use this to be my wiring to the One Wire Digital Temperature Sensor - DS18B20 SEN-00245 My idea to use steel wire is that steel is a poor conductor of heat but reasonably low resistance. I want to keep the tiny SEN-00245 isolated from the wires - meaning I don't want my hookup wires acting like a little heat sink. I'll report back how well this works after I get the steel wire in hand, it is on backorder for a week. Having fun, Plinker Craig

    big question is can you wash it

  • unroll & use old fashion silk isolated AM antenna bobine instead of this. This is the cheapest and best solution! Before using it if you would like to you can colour it also...

    Which "entire spool" is this a smaller portion of? What is the resistance per foot? I'm very interested in sewing more circuits into clothes, but wonder about washability-- how does this stand up to (gentle) machine washing? Thanks for any details you can offer!

    • I added some information above. The resistance is measured at about 28 Ohms/foot. We actually don't carry the larger spools of this thread although we may in the future depending on demand. Being made from stainless steel fibers it holds up very well to gentle machine washing, although depending on what components you sew to your project you may consider hand washing for their sake.

        Any update if this is carried in a larger spool? I would love to have a larger spool too.

quick shipping ... product as described ... works well ... have enough left over for more projects!

Simply works!

... to make touch-capable gloves at very low cost.

Great for wearables

This thread works great in wearable projects and holds its knots a lot better than conductive threads that I've tried from other companies.
