No, fasteners = screws.
I've heard of using angle (tabs) and keeping the UHMW free-floating, so to speak.
The problem there I would think, is that the bare aluminum tabs would hang up (on rocks). It might be possible to rout the edge of the UHMW and let the tabs in so that they don't project.

Something else to consider is plastic laminate (Formica).
I know of an old Wooldridge DB that used it with good results.
You still might want to coat the bottom of the chines with Gluvit, though.
