Default Fly Tying Threads and their Measurment Systems

The larger the "Denier" number, the heavier the thread...etc.


In the older and less accurate system for measuring Fly Tying Thread, the "aught"( 3/0,6/0, 8/0, etc.) system, 6/0 or six zeroes indicates a heavier and stronger thread than 8/0 (eight zero size thread)

In the Denier system, 40 Denier to 55 Denier thread would be used to tie flies on hooks as small as
#18 etc.

The newer system of measurement is the following:
"Denier is defined as the weight in grams
of 9000 meters of nylon, polyester, rayon thread, etc."

An 8/0 thread in the "aught" system equals 67 Denier.

A 6/0 thread in the "aught" system equals 143 Denier.

3/0 is very heavy thread.
A 3/0 thread in the "aught" system equals 176 Denier


Sewing Thread "commercial sizes" for heavy-duty thread used in upholstery and webbing (e.g., safety rigging and vehicle tow straps) are 33, 46, 69, 92, 138, 207, 277, 346, 415 and 554. These sizes are the denier measurement divided by 10.

************************************************** *********************

More Info:


The denier system of measurement is used on two- and single-filament fibers. Some common calculations are as follows:

1 denier = 1 gram per 9 000 meters
= 0.111 milligrams per meter

In practice, measuring 9000 meters is both time-consuming and unrealistic; generally a sample of 900 meters is weighed and the result multiplied by 10 to obtain the denier weight.

"Denier? Ain't that some River in Egypt? Yeah, they named that River after that famous Egyptian Pharoah, Denier III er sumpin'!"

Hi Bruce,

I saw the post title and went looking for some info for you, then I clicked the thread and found out you had already done the research and posted it here oops. Anyway I copped this off of another thread and maybe it will be helpful to someone also.

Thanks HardyReels. That is a great addition to the subject.
I like the "hook" visual.

Poor quality materials are destined to discourage beginner tiers and cause greater expense when the time comes to replace them.

YOUR way is not the ONLY way when tying flies!

Fly tyers can be masters of making things complicated!

You're only limited by lack of imagination. Be creative, experiment.

FlyTire:

That is really a terrific link. It cites the one bit of information that I have been chasing all over the Internet; "Breaking Strength".

Very appreciative here of your information. Thanks.
