My airplane has a two piece fiberglass cowl. The lower sections bolts to the fuselage and the top section bolts to the bottom section with non-captive screws that screw into nutplates attached to the inside of the lower cowl. There are four screws on each side, so a total of 8 screws hold the top cowl on.

i don't really like the non-captive screws and it is not unusual to lose one in flight.

I'm interested in your opinions on what to replace them with such as dzus or camloc or something else.
