High temp (400 F min) caulk/silicone/sement/glue - possibly drill-able?
Does anyone know of a product that is similar to silicone caulk that is moderately heat resistant and is drill able (possibly able to anchor a screw
into it)?
I need a fair quantity of 12-28 oz's.

In terms of 'similar' do you mean in terms of application, color, chemical resistance, elasticity, etc? You're going to hit the most points just with
a standard high-temperature silicone like Permatex Hi-Temp, but I am not sure if that is going to be sufficiently structurally sound enough to anchor
into. Then again it all depends on your surface area contact and if you're doing this smart enough if the anchor will hold. For example if you
undercut whatever area you are filling in with silicone so that the seam/hold gets larger toward the bottom then it will wedge itself as upward
pressure is applied from the anchor. Personally I used to use fireplace cement for high-temperature applications but those were much higher than
400F, and at that temperature you won't even be able to cure fireplace cement.

I was hoping that would work as I was REALLY impressed with it last time I used it. It's amazing stuff! When I looked at it prior to posting the
page quoted 300F max temp but after looking at other sources I see that it is 500F sustained and 600F max. - looks like the first place may have had a
mistype. Thanks for the suggestion.

I considered fireplace cement but don't know how it dries. What I'm looking for is to be able to seal Al pipe on the end (max 1" deep in depth &
max 2" diam). Water will flow through and carry heat away - heat source should be no more than 500F on VERY rare occasions and for short time -
normal temp probably 300-350.
As far as drillable/mountable, it should be able to hold a wood screw if possible (this is the least important aspect and can be ignored if a superior
alternative is available as other options for connecting/mounting are available).
