Lan:

Don't dismiss screws to hold it shut. If this were a hatch needing to be opened constantly, the spring latch, a turn handle, so forth would be worth while. Or if you just want fancy, the spring latch is worth while.

If you just want to hold it shut, screws are hard to beat.

Here's a couple pictures of the Tiggerkitty, showing the nacelle hatch open and shut. Two screws.
