Quetsion about transome door latch hardware

[The machine]

Does anybody know the size of the screw and captive nut that hold the transome door latch on, on a 270 Sd. This is a pem type nut and a philips head flat head screw. The boat is at my summer home and Searay has no part number or description for this.

Does it look similar to this? It's 8-32 thread (stainless).
