Nano Silk Pro 20D is designed for micro flies down to size 32, however do not be fooled, Nano Silk Pro 20D Black is as strong as 8/0 polyester thread yet is less than 1/20th of the diameter. As a result it can be used for any fly where you do not want to see your thread.
You can tell you are using Nano Silk Pro 20D as it’s on white spools to differentiate it from the other Nano Silks. Please remember to use a ceramic bobbin holder.
Because Nano Silk lays perfectly flat you get no thread build up. Indeed check out our Youtube video where we put 100 wraps on a hook and still had no head build-up!
24/0 20 denier thread
Breaking strain 750g / 26oz (1.65lb)
Perfect on hook sizes 20 to 32
Lays perfectly flat with no build up, regardless of how many loops you put on the hook
10 times stronger than steel of the same diameter
Pro Tips:
1 - rotate anti-clockwise to untwist and lay perfectly flat. With just 2 or 3 light wraps of Nano Silk over foam you can then tighten and tie in foams or materials that would cut easily.
2 – use white Nano Silk and simply colour the last 4 inches (100mm) of thread for heads in a visible colour
Not all GSP threads are the same as strength tests show. We use the highest quality materials to ensure that there are no tangles and that it produces the smoothest and strongest GSP on the market. Search for Global Fly Fisher Thread Chart to see independent evidence!.
Note: with all GSP threads including Nano Silk Pro 20D Black you should always use a ceramic bobbin holder.
There are 100m / 109 yards (approx ) per spool of Nano Silk Pro 20D
