I'm installing a set of microburst led strobes onto an already covered plane with fiberglass tips. They didnt include any hardware. The holes inside the housing are tapered. There's really no way to access the inside to install a nut or backing plate to use a 4-40 machine screw. Curious what sort of ingenious methods anyone may have found to attach it before I just use a wood screw.

How thick is the fiberglass? If it's reasonably thick, you could use threaded inserts into the fiberglass, and install them with epoxy for added security. Or you could just drill and tap the fiberglass for a machine screw. I don't like wood screws in fiberglass, they tend to crack the fiberglass.

What about cutting a larger hole where it will be covered by the light? Then you could access the back side through that hole, maybe enough to glue a nutplate.
