Re: Joining polycarbonate /Perspex panels to make a case?
Yes ypu can make decent threaded fastenings into Perspex/Lexan: you drill a hole and then fit a brass bush.
The ones I used [though for the life of me I can't recall the name of them] were a tubular Brass threaded insert - the first third of the insert being solid, the remaining 2/3 having four slots cut in the sides. The entire thing was knurled on the outside.
You drifted them into a hole drilled into the Lexan, then when you screwed the screw into the thing it splayed the four sides of the part that was in the bottom of the hole out so they grippped the plastic.
A few minutes with your favourite search-engine will show options like those in the attached pics.
