Hi, we need a couple of AN224-3 fasteners for a part we're overhauling. These are part of a "press-stud" type arrangement. We only need two, but cannot locate any. Anyone have or know of some? Any ideas very welcome.

Thanks

That spec is obsolete and I can't find a crossover to a later NAS spec. Can you provide a photo or a better description? What are they used for?

They're used for attaching control column boots to parts - in this case the control column boot for a P-51 - these attach to the main control lock casting bracket. These part attach to the bracket by way of a 100 degree countersunk screw. The boots contain the second part of the clip which then is pushed onto the AN224.

Hope that makes sense!

Otherwise search ebay US and UK might get you the lift the dot stud types.

Thank you gentlemen, that's a great help. Certainly helps plug the information gap.
