small self taping screws

[Silas Gull]

Hi All,
I have an up-coming project which will involve fixing some plastic trim to some flat aluminium bars. The trim is a 2 piece H joint extrusion, see link http://www.tubewayextrusions.com/plastic-h-section.html
The base thickness is about 1.5 mm, and as it is going to be load bearing, I will need to screw it to the aluminium.
I need some small gauge self tappers, preferably ones that are countersunk.
Can anyone point me in the right direction?
Many thanks

Lion picture framing supplies does a pretty good range of tiny csk screws - not specifically described as self-tappers but I suspect would work fine in aluminium.
