KR> Nuts and bolts

2009-01-28 Thread Ed Janssen
Pat,

Regarding the cotter (not "carter")  pin hole - fiberlock nuts should 
probably not be used with a bolt having a hole within the threaded portion. 
The thought is that the sharp edge or a burr around the hole could damage 
the locking ability of the fiberlock, especially if the nut has been removed 
and put back on several times.

I am still going over a project that I purchased last year, taking things 
out that don't suit me and such.  So now I have a couple of questions.  The 
wheel attached to the landing gear main has four bolts with fiber lock nuts, 
is this acceptable?  There is carter pin hole in the bolt, nor safety wire 
hole in the nut.  Next, how do you clean the journals of the crank after 
nitriding?  I don't have a lathe so can't mount it and polish that way.

2009-01-27 Thread Ronald Wright
Hi Mark,

Went in and looked at your engine/plug photos.  I've run auto fuel and 100LL in 
my A65 and have always run Marvel in it.  No build-up on plugs or pistons.  I 
use it in the oil and the fuel.  Never miss adding and I think it really 
works..  Seems to keep the build-up soft so it continues to blow out.  I do run 
the engine wide open throttle a lot which I think helps keep the temps high and 
cuts down on the junk accumulating.  Just my .02..

Maybe I missed your point...the two wheel halves on my certified Clevelands

Fiber or nylon lock nuts are the norm where no rotational forces are
involved.  As the the bracket or gear leg are fixed items, so these nuts are
what you would use.  The fact that the bolts have a hole probably just means
the previous owner didn't have the correct bolt lengths on hand without
holes.  They will be fine.

My axles are also attached with nylocs, and they haven't fallen off yet 
after close to 2000 crappy landings.  It should be easy enough to buy a 
castellated nut and drill a matching hole for a cotter pin for the axle nut. 
I used a strip of gray Scotchbrite Ultra Fine pad to see-saw a nice finish 
on my nitrided crank in just a few minutes.  You need to clean it thoroughly 
afterwards to get the abrasive off of it by doing something like a rifle 
brush through the oil holes in a vat of kerosense or diesel fuel.  I think I

One resource for technical details for US screws (mostly not

If you do a search for "screws", the first item to come up will be 
the selection list, with an astonishing array of types. Once you get 
down to a specific type, the catalog pages will usually have 
technical details for them.


For an example of mind-numbing detail, here is what comes up for a

About the 3rd hit had the title: "Aircraft Hardware - What you need to

Click on that one and about one or two pages down you
will find: "Figure 2: AN Aircraft Bolt Dimensions"

Click on that one and you get a whole table of dimensions.

Perhaps that helps. Otherwise, there are beaucoup more

My Tony Bingelis book with all the good info is loaned out at the moment
but here are the basics:

10-32 is the "fine thread" series of bolts as used in aircraft.  It 
is 3/16" in
diameter with 32 threads per inch.  It is usually referred to as an AN3,
indicating it's diameter in 1/16's of an inch.  The next size larger would be
an AN4 (4/16" or 1/4 inch).  The dash number following the AN3 would
indicate the length in 1/8" increments  The A , H, or no letter following
the - number indicates whether the bolt has a drilled head, a drilled
shank, or not drilled at all.


>2 - The AN system starts at AN3, which is 10-32. What would be the next
>smaller size in the standard Imperial system?
The next size smaller here in the U.S.A. would be a #8 with 36 threads
per inch.  I'm GUESSING that to be a 1/8" bolt / screw so whatever your
equivalent to .125" should be close.  We don't use that size on anything
structural.  What is your intended use?

So much for GUESSING!!

According to the chart that  Matt pointed us to, the size for a
#8 would be  0.164".  I need to quit loaning out my
Tony Bingelis books I guess.

My original question still stand though.  What is your intended use?

KR> Nuts and bolts

2008-10-12 Thread Brian Kraut
As others have answered, 10 is the diameter and 32 is 32 threads per inch.
I have no idea what the 10 stands for, but going smaller than that in screw
sizes you have 8-32, 6-32, 4-40, and 2-56 as the common used screws.  The 3
in AN3 is 3/16" diameter and that refers to the size of the shank of the
bolt.  Going bigger than that you have AN4 which is 1/4" (4/16), AN5 as
5/16", etc.

For your second question there really is not a smaller bolt than an AN3 that
I am aware of.  Smaller than that they are screws, not bolts, although there
may be some special odd bolts smaller than that but they are certainly not
common.

Subject: KR> Nuts and bolts


Could somebody well versed in the secrets of the Imperial system tell me:

1 - When a thread size is expressed at, say, 10-32, what do the "10" and
the "32" stand for?

2 - The AN system starts at AN3, which is 10-32. What would be the next
smaller size in the standard Imperial system?

Wow! I never expected such a debate on what I thought was a simple 
question!

OK, let me explain what I am up to.

I am trying to order replacement screws for my Zenith/Stromberg carburetor 
(so, Larry, you may stop worrying about me: it IS non-structural indeed). 
Now, the bottom part of the carb is secured with long, thin machine 
screws, which are of a diameter of roughly 3.2mm, if I remember well.

Obviously, to order that, I needed to identify the screw size correctly 
(remember, I live in Europe, so non-Metric things must be ordered from the 
US by mail order, and the order must be right first time, otherwise...I'm 
screwed!).

With metric screws, this would be a non-issue: take a caliper, measure the 
diameter in millimeters, period. But US machine screws seem to have 
obscure names, like  MS35206-203, and even more obscure size names, like 
2-56 or 8-32. So, I was definitely lost. And yes, before I asked, I did 
check in Tony Bingelis's books, and also the AC-4313 1A, even in the 
Jeppesen sheet metal course, and the Internet too. Lots of data on AN 
stuff, but I could not find any explanation on the machine screws 
measurement system.

Now, I then noticed that the smallest AN bolt size is also defined the 
same way (10-32). Hence my question: what do the two figures mean, so that 
I can understand what is what in the Imperial system, and make sure I 
order the right stuff.

I am now pretty sure the correct size will be 8-32.

Thanks for all the help, guys.

Now, for fellow non-US builders who are also lost in translation, I 
compiled a Microsoft Excel table of the AN hardware sizes which gives 
Metric measurements. Anybody interested, just shoot.
