(Solved)Tee Dee .020 tank screw

Super Dave,

There appears to be only one that goes through the center of the backplate. That is the one I am missing.

Ron:

My PeeWee .020 is firmly attached to a plane so I'm unalbe to check the screw dimension.

Have you checked with Bernie or Matt? Bet they'd know. Besides I sure there are other things that you need from them too. (Doesn't everyone?)

SD,

Are you saying, the pee wee tank screws are the same as the one on the tee dee?

I suppose this is my fualt,
Once again sorry Ron i thought i included everything.

You sure?
I feelin' bad!
Tell me if a pee wee screw fits and if i find one i will send it over.
(for free of course)

Nitro,

Don't feel bad, it's only a screw. It wouldn't be worth the cost of shipping. I do appreciate the offer though.

Ok then but trust me I don't mind shipping one if you want it.

I just measured one and its 2 – 32 X ¾. Might be hard to find .

I have a chart about the screw sizes:

Nice chart. There are always questions coming up about screw sizes.
I can offer two additions to the chart.
The Tee Dee .020 tank screw (as stated in above post) is 2 – 32 X ¾.
The Tee Dee .010 tank screw is 2 – 32 X ½.
Considering that 2 – 64 is UNF and 2 – 56 is UNC then 2 – 32 looks like a sheet metal screw by comparison. But on closer inspection, it is truly a fillister head machine screw.
I can’t tell if the female threads in the forward part of the tank were molded/taped during mfg or were formed by the screw at initial assembly. One of the screws has a slight taper on the first thread but the other is fairly square. They are definitely not self-tapping screws.
Regardless of how they were formed, the female threads are now nice clean 2 – 32 tpi and will only accept the corresponding screw (without damage).
Al

Wow!

Lot's of good info. Thanks gentlemen!

Well,

No 2-32 screws at the hardware store. They had 2-56 though. I'll keep looking seems common screws start out at #6 or 8. I have checked Matt and Bernies sites and don't see anything specific. Am I missing something? I have a list of stuff I need to buy and was hoping to add the screw into the order.

Ron, I was in error when I described the screw as a machine screw. It is a No. 2 (.086 dia) screw, it is 32 threads/inch and has a fillister head but the thread form is not a machine screw. It actually is a standard sheet metal screw.

Toward the bottom of the page look for a thread chart for a ‘Type B’. They show a 2 – 32 and a sketch. That is the thread that you are looking for. Sorry for the misinformation.

Al,

I placed an order with Matt, he said he would throw one in with the order. It's not listed on his site but, I guess he has a few available. I thank you for your help and knowledge. I also appreciate the link as it may be useful to myself and others.

Will throw a couple in Ron. Guess I should put them up on the site

Thanks Matt,

Much appreciated.

Just received my order from exmodelengines. 3 new backplate screws. Worked great! Thanks Matt! And as always I appreciate the extra .049 goodies that are thrown in free of charge.

What kind of goodies?

.049 tank gaskets and head gaskets. Plus the screws were free as well. Good guy that Matt fellow!
