Heavy Tenara® Clear Lubricated Lifetime Thread 8 oz. (950 yds.)
SKU: 103320
4 Available


Tenara Lifetime Guaranteed Thread features unique PTFE (polytetrafluoroethylene) fiber construction that extends the life of fabric seams and ultimately the products in which it is used. GORE® Tenara has high strength and durability that for over 10 years has proven to be unaffected by exposure to UV rays, cleaning agents, pollution, saltwater, air, rain and snow.

Great for outdoor, awning and marine applications, Tenara thread will not rot if left outside all year round. It remains colorfast even in extreme temperatures and frost. Although more expensive, Tenara is a greater value than other polyester threads when considering life span and re-stitching costs. Choose Tenara thread to improve the performance of outdoor fabrics where seam life and integrity are of the utmost importance.

Tenara M1000H is similar in weight to V-138. Heavy Tenara thread requires a needle size of #19 or #20. Smaller needles may cause skipped stitches and/or the double ply thread to unravel above the eye of the needle. Tenara thread does not require as much upper tension as normal polyester thread. Heavy Tenara thread usually requires less tensioning which will result in a good-looking stitch on both the top side of the fabric and bottom, but the knot on the bottom side usually does not pull up into the fabric all the way.

We recommend using Tenara thread with rotary hook sewing machines like the Sailrite® Fabricator®, 111, Professional and Big-N-Tall. Not sure if your machine has a rotary hook? Learn more in our Rotary vs. Oscillating Hook Sewing Machines article.

I Really Like This Thread

I've come to really like working with this thread, particularly the clear "color". I go back and forth between this and polyester thread on my Consew machine without any accommodations or adjustments - the machine doesn't seem to care. Most of my work is for outside projects and I use it more often than not - if you want the product to last it's hard to justify using the polyester. One odd thing...a hot knife won't cut it without burning the surrounding fabric. When trimming edges with the hot knife I run through the fabric and go back and snip the threads.

Tenara heavy clear thread.

After reading all the reviews on line and talking to Matt Grant I decided to order some Tenara heavy thread for exterior canvas projects. I purchased the heavy because the size is close to the standard V 92. Ordered clear and was expecting something like fishing line but was surprised to see a twisted thread. Using it in a commercial Juki machine with a size 19 Serv 7 needle and pulling the thread off the top of the cone. After a few rows of stitching and tightening the tension about two turns it sews just like any other thread. Saws through two lares up to 8 lares with no further adjustment needed. Very happy with the purchase after hearing so many people say it was hard to sew with and skipped stitches. So far no skipped stitches when using straight stitch. Have not tried zig zag yet. Should make my projects last a lot longer in the Arizona sun. It really isn't clear but a milky white. Think I will order the other colors.
