Anybody know what size torx screw is in there?

 

Do you have a set of Torx Bits ?

Try them one at a time until one fit the best.

Sorry I had to do it !

Torx Bits are a good thing to have in the tool box so it will pay off to buy a DECENT set.
China made or cheap too, especially Torx Bits will break almost as soon as you put them in the Bolt Head.

I tried the ones that have the bit that slide in and out... JUNK, I got a set of Craftsman's from a Sear's sell-off and they have worked great not one breakage.
I even use the large one on the bed bolts with one breaking ot stripping out.

Go buy a good set and you won't have to ask about Torx Bit sizes again !

 

T20. the screw is set so deep and the opening narfow enough that my torx ratchets cant get in there. I finally got it done though.

Good that you got it done !
