Default What sizes do we need?

I have the same issues with Phillips head screws and this thread made me wonder if anyone made mil spec screws with a Torx head. I managed to track down the manufacturer that make the screws that Aircraft Spruce sells. I asked them if they make an AN515-8R8 with a Torx head (I figured the AN515-8R8's were the most common screw on my RV and a good place to start). They said no, but that they could make the same exact screw, plating and all, with a minimum order of 5000.

Since this is a few more than I need, I contacted Aircraft Spruce's main office and asked if they would be interested in adding them to their product line. They said that they would be very interested in adding them because they've had several inquiries for Torx head screws. They requested that I supply them with a list of sizes we need.

I'm not looking to replace every screw on my airplane, just the ones that come on & off like access plates, floor pans, etc.

Is anyone else interested?

This is what I have come up with so far for sizes, is there any I should add?

AN515-8R6 Floor pans - 3/8" long (cad plated)

AN515-8R8 Floor pans and many other places (cad plated)

AN509-8R8 Access plates (cad plated)

AN507-6R6 Access plates (cad plated)

AN507C-632R8 Wing tips (stainless)

AN507C-832R8 Wheel pants (stainless)

AN526C-832R8 Spinner (stainless)

I would buy them if Aircraft Spruce sold them.

I've already bought a bunch of -8 and -6 torx screws out of stainless, but for some applications it would be better to have cadmium plating. I'd buy a few hundred of these.

this looks like a nice business opportunity for somebody.
or it could be a nice area of easy improvement for van's kits.
upgrade the kits to torx head screws and at the same time become wholesaler for the aviation torx screws.

not planning to replace too many now that the plane is flying... maybe just a few access plates, cabin floor, wheel pant, and such screws.

rgds, bernie

I too have purchased some stainless screws with torx heads but they didn't seem to be up to the AN/MS quality. It would be nice if Spruce would duplicate their entire line of screws in torx but for now they've agreed to look into adding the ones we say we need.

I'm not sure that I've hit on all the most common sizes so please look back at post #21 and let me know if I should add any sizes.

Also, I'm going to request that they use the same numbering system and just add a "TX" to the end to make them easy to identify. Being that the military specifications may be call for a Phillips head they may not be able to use the "AN" or "MS" designation. If that's the case, I'll request the drop the AN/MS and replace it with a TX and keep the rest of the part number.

I'd love to purchase a 7/9 kit with replacement torx screws for all the removable panels. Especially the interior ones.

its been too long since building...cant remember how to decipher the codes for screw type and size that you provide. What I do remember is that all the screws Vans gave me for the seat pans in my -7A were 1/2 inch long, when 3/8 was actually enough to fully penetrate the nutplates. That makes for a lot of unneccessary turns of the screwdriver. Do you have 3/8 inch long Torx screws suitable for seat pans included in your list?

I will buy them if they are not stainless, and the price is competitive with the standard Phillips head screws.
