Fly Tying Thread Table


Published Jun 13th 2014

Manufacturers, materials, diameters, breaking strengths and much more for a large number of fly-tying threads

By

This table tries to summarize all available data on all current (and some discontinued) fly-tying threads and accompanies the article on the subject of tying threads.

Much of the information presented here has been compiled from whatever data was available from the different manufacturers and their distributors and dealers as well as some independent sources. Care has been taken to double check everything, and whenever there were different specs on a thread, I have taken the one that gave the most benefit to it - not that this is necessarily right, but to be fair and let the doubt benefit the manufacturer. Many manufacturers don't specify the physical properties of their threads - like thickness, Denier, breaking strength, material or production method. Some are very secretive and some simply don't have the information commonly available. The various columns are explained below the table.

Material
Mono is monofilament nylon. Silk is natural silk. The rest are synthetic multifilament threads produced using different methods. Two threads made from the same material can be very diferent.

Aught
The most common way to indicate thickness. Not a physical standard. Larger number means thinner thread, so 8/0 is thinner than 6/0.

Denier
The weight in grams of 9000 meters of thread. A physical standard used in the textile industry, but not an indication of thickness or strength.

Dia
Diameter in millimeters (mm) or thousands of inches (.000"). As specified by the manufaturer or measured by me or others.

Breaking
The breaking strength or test of the thread in grams (g) or ounces (oz). The number is the highest found if values from different sources differ.

Relative dia
A visual indication of the relative thickness of the thread compared to others. Not to measure in any way! Just a visualization.

Denier/mm
A simple calculation of what the Denier would be if the thread was 1 millimeter thick, and a way to compare the Deniers for the different threads. Ideally this number should be the same for threads made from the same material, but the numbers clearly indicate that the Denier number does not help us much in comparing even almost identical threads. Denier and thickness are NOT correlated.

Denier and thickness are NOT correlated.


Absolute strength*
The absolute breaking strength of the thread compared to all other threads and not taking diameter or material into consideration..

Relative strength*
An indication of the relative strength of the thread compared to its diameter and the other threads. Not an absolute measurement! Thin threads can be as relatively strong as thick ones. The numbers indicate breaking strength in relation to diameter.

Flatability **
The thread's ability to flatten when tied in. Sometimes requires the thread to be untwisted.

Splitability **
The thread's ability to split when used for the split thread dubbing technique.

Smoothness **
How slippery or smooth the thread is against the hook shank or materials. Its ability to "grip" materials.

* The textual strength indications are based on calculations and data comparisons and the groups are defined by the me. They are objective, based on numbers, but you may disagree with my scale.

** These properties are assessed by me based on threads that I have tied with. I have only added data for unseen mono threads, which are basically all very smooth, round and can't be split.

Disclaimer: I have researched very thorughly to collect and confirm the data in the tables, and gathered and compared and averaged numbers and information from many sources - and measured thread myself when possible. If numbers have varied, I have selected the "best" number for the thread (thinnest, strongest). I'd be very happy to get missing (or more correct) numbers from the manufacturers who haven't published such information - or from other tyers or dealers who have measured or tested the threads. The more precise this info, the better for the fly-tyers. Contact me on martin@globalflyfisher.com.

See the main article for more on tying threads.

Work in progress
This article on tying threads and all the data that is part of it is work in progress and will be updated as soon as I get more or better information on the various threads.
If you have things to add, comments or corrections, feel free to contact me on martin@globalflyfisher.com. You can also leave a comment to the article, and I will see it and respond if required.
I welcome contact from tying thread manufacturers with information, specifications, remarks or corrections - even criticism. The more the better!
