Description: This is about 360 yards of conductive thread spun from stainless steel fiber and wound on a spool. You can use it as a creative way to connect various electronics onto clothing projects. This large spool is a great way to get into wearable electronics without a large upfront cost and a large enough quantity to not be afraid of making a few mistakes.

What sets this thread apart from the other conductive thread that we carry is the fact that it’s actually spun from stainless steel fibers (as opposed to plated silver) 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. Also, it’s somewhat ‘hairy’ and can be slightly more difficult to work with in close, fine conditions than the other thread. Our resident E-Textiles expert suggests waxing the thread for hand sewing, as this should take care of any ‘hairy thread’ issues. Since waxing is impractical in machine sewing applications, avoid sewing close connections by machine as the ‘hairs’ could potentially short across small distances.


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

Customer Comments

  • Hello, is this the same as sold on the bobbins? What is the aproximate length of the 60g spool? I am looking for an inexpensive thread to use for projects at the school I occasionally work at. Is it easy to handle (rigid, easy to sew)? Thanks :-)

    //Edit: In another webshop I have read ~360 yards, is that realistic?

  • can i use this to sew in my backpack..? i have a project to be made and i need to use this thing..answer me asap because i will buy.

    • You should be able to use this for pretty much anything you would use regular thread for. Its a little thicker, but as long as you know how to use a needle and thread you should be able to sew this in your backpack.

  • will this thread heat up so that it could be used with thermochromic paints?

    • Anything heats up if you put enough current through it (as long as it is not at near absolute zero temperatures). The question is how much current is required to get it to heat up to a noticeable value. So what the resistance is would be a good question that I would also wonder. Are there any data sheets on this?

      • The resistance is 28Ohms/ft. If you double up the thread, that cuts the resistance in half.

        • Simply doubling up the thread won’t work. 2X the tread means more current needed to heat up the thread, I’m not sure how much more current though.

  • Is there a data sheet for this? I’m interested in the current limit.

  • I wonder if this would work for creating lighting stikes if you tie one end to your model rocket?

Good conductive thread

I purchased a roll for the maker club I run and it worked great the kids had a lot of fun making everything from light up bracelets to bow ties.

Works, but somewhat weak.

It’s a great quantity for working with classrooms and maker spaces, but its tensile strength is somewhat low. Even sewing something simple I managed to break it a couple of times. That’s frustrating for me and young people.

Sorry to hear that the thread would rip on you from time to time. It’s a decent thread, but certainly different and slightly more fragile from your standard spool you might find at a craft store.
