Hi,
I have been looking for some time for spare nylon wing bolts for my Sebart MythoS Pro.
So far without success.
It is close to (but not exactly) metric M6 thread, I suppose it is UNC threads.
I took a photo of one of the two nylon wing bolts I have, what is the dimension (threads) I must be looking for?
If anyone have a link to some website that sell this type of nylon wing bolt it would be great. Thanks.

SAE: count number of threads per inch (1/4-20 has 20 threads per inch, for example)
Metric: measure space between threads (M5x.50 has 0.50 mm between threads).

Metric sizes have half sizes, so it could be M5.5 or something.

Edit: I would have assumed they were metric, but looking closely at the pic they look like SAE threads. Tough to tell.

I have these, I can measure them tomorrow for you, but these look like a finer thread:

Hi JetDesign,

The wing bolt You gave a link to seems very similar to the one I ordered from a company here in Sweden (it was metric M6), it do not say what threads the black nylon wing bolts have in the link, for "30 cc Plane Models" is all they say.

Deleted ! Was not aware of your location. U can use plastic bolts from most plumbing departments at hardware stores. I can measure the one on my Wind S later today and give you the thread pitch plus thickness...

Unfortunately they are not perfectly round:
Major Dia = 0.22-0.23 (5.25-5.80mm)
Minor Dia = 0.19-0.20 (5.0-5.4mm)
Threaded length = 0.92 (23mm)
Length of major dia = 1.09 (27.8mm)
There are about 24 total number of threads (I don't know how to count in metric )

I have one of the 30cc airplanes from that site. SDS hobby sells the same airplanes. They seem to carry the wing bolts too and actually list the size. I thought it might be better to try somewhere not in the US?
