I do not recall anyone finding torx head cap screws but Fastenal has a good selection of allen stainless button head cap screws. They are offered in a black oxide finish if you plan to paint them. Somewhere buried in my build thread, I posted results of torque tests I did on the allen heads along with pictures.
This link takes you directly to a cap screw close to what you need, it may be too long for your needs.
You can start here and select the parameters of the screws you want,
