pan head screws

[Bootlegger]

 Is anyone using pan head wood screws in modeling and how well do you like them?  I am thinking about using them on some Cox powered models,  your thoughts and suggestions please      obliged

If you mean for mounting engines I would recommend using sheet metal screws instead of wood screws.
You'll be fine.

That reminds me of the old Soviet engines with pan head / straight slot screws. Those were special because first you couldn't tighten them, and then you could not open them.
But more seriously, if you are comparing between cylindrical vs. pan head Allen screws, the pan head ones often have smaller/weaker key hole that tends to fail when you least expect it. They're ok if you only need to tighten them once. L

rc allen head servo screws work great for cox reedi's

I like the Allen head lag screws sold by Dubro, et al in the 2-56 size for mounting 1/2A engines and other small things.

Cannot imagine using "pan head" screws for mounting a 1/2a engine. Fillister head, perhaps, but never pan head. Socket head machine screws would be my choice. There are places where I might use "button head" screws (Lauri called them "pan head"), but the ones you run with an "Allen Wrench" or "hex key" are always referred to as "button heads" 'round these parts. I suppose it could be different on the East Coast and Europe. Lauri is correct in being suspicious of them.    Steve

I have several in a few sizes and I do not like them becaus the hex indent is shallow and any back torque resistance stripps out the head

Fred: good-looking .051 you got there!  Tee-Dee or Medallion or something else?

[Fredvon4]

Assembled out of NOS and custom Cox International anodized bits
TeeDee/Medallion Crankcase. New unrun .051 Piston/Cylinder that needs rebluing

Eventually I will set up to anodize and powder coat... I desire a Red, White, and Blue set of TeeDees

I've used pan head screws on up to 60 size rc planes many yrs but only in nylon mounts. No problems. Sheet metal or wood doesn't matter. They should work on 1/2a in wood but it's already be said that you could risk fuel saturation problems.
