Storm Window Screws

[M20F]

What’s the PN on Spruce or elsewhere?

AN526-632R5 (6-32 machine screw x 5/16) is what's in my E

@M20F, that's the same screw I have in my C. Not only do neither LASAR nor Great Lakes have them, but LASAR claimed they are aftermarket. It wasn't until sevetal months later that I saw my parts manual shows the one screw, while LASAR insists there should be two small screws per side.

A friend had two brass screws left over from making a holster thst screw together similarly. I had to shorten the screw some tomfit, but it works fine. Looks a little funny with ine aluminum unut and one brass one, but who looks that closely anyway? I can check the Parts book tomorrow if you still need the number . . . . But it may not be available.

Expect GLAP might have them... the window people...

Nope. Like LASAR, they insist that all Mooneys have 2 tiny screws rather than a single larger one.

I bought mine on the aviation isle at HomeDepot.

According to my M20J IPC, the screw is a standard 6-32 MS24693-523. The nut is a Mooney part 914071-005. LASAR website lists that part at $45.69 ea. There is also a 7615 washer $0.10.

Wow! I'm pretty sure HD has them cheaper.

Caution, Reviews say these rust and are not stainless steel.

I got a PM from a Canook A&P who had the solution.  Thanks for all the replies.

I just used standard cad plated MS aviation hardware with the locknut on inside. Not quite as pretty but available and functional.

What was the solution?

[N201MKTurbo]

 

These may work. You could use the nut on the outside and an oval head with a finish washer on the inside.

These work just fine. Newer planes use four small ones, my 1970 C uses must two larger ones (even though Dan at LASAR insisted that it must be missing replacement window, it matches the IPC with two screws).

[good2eat]

Our local Ace hardware had them.  Worked perfectly - under $2.00

@M20Doc do you remember the solution?

[Guest]

If I recall it is a tubular nut with a countersunk slotted head made of brass.  It’s meant to fit in a countersunk trim washer.  I might have a few in my junk drawer in my tool box.

I haven’t looked, but wouldn’t sex bolts work?

Perhaps a choice here under "Binding Barrels and Screws"...

Most are sex bolts AKA barrel nuts and Chicago screws, but barrel nuts often are something different.

Whenever I see this thread pop up in the "Recent Topics" window I think it says, "Storm Window Screens", and I think, "It's about time somebody invented that for airplanes..."
