need source for long self-tapping screws

Hi, all -

I'm installing something on top of my bed rails. In drilling down into the rails, I don't seem to hit metal until I get about 2" deep (including the equipment I'm mounting), as the upper part of the rail appears to be some composite material.

Does anyone know of a source for #14, 2 1/2" self-tapping screws? I suppose there's probably a reason that they're not really common (didn't find them at Home Despot), but I have no options that I know of. I can't get to the underside, so a bolt/nut option is out.

Thanks...

I would try an independently owned hardware store, as they tend to have a bigger delection in nuts and bolts.

maybe use a molly bolt.

Screws such as you are looking for are often used to attach wooden floors to trailer frames. They are available at several trailer parts dealers. The link below is to TJ Trailers who have them in a couple of sizes. These are black oxide and require a 7/32nd hole but they are self threading.

McFeely's also sells a self-tapping screw for trailer floors that you might be able to use.

Their self-tapping hex screws would be perfect, if they came a little longer (they stop at 1 1/2").

I like the ideas...please keep them coming.
