-1987 Carver 4207 Shower head replacement?

[steve&tammy]

Hello all!
Ok, so we just got back from a great weekend on the boat and forgot to bring the shower head(s) with us to see what 'size' they are.
Both shower faucets work well, both lines from faucets to heads are good but we'd like to just replace the head and as you all know, the current heads come with that handy little "hook onto the other thingy on the shower wall holder"
Therefore, we're wondering if the current 'male' connection that does indeed have that 'eyelet' to hook onto the wall, is a standard size?
Meaning, if we JUST purchased a new shower head, can we just unscrew the old one and screw on the new one onto the same, factory setup?
Thanks in advance!
Steve & Tammy

In my 405 i just replaced the head and kept the oem fitting with the hanger. Standard 1/2 " threads.
