Hi there,

I have an Aquatica AD500 housing, and I was just trying to screw a tripod mount onto the bottom, and I can't seem to get any of my 1/4-20 screws to go in any further than about one turn! Is there some obvious fact I am missing about the screw holes on Aquatica housings? Is there usually some sort of forcing that needs to be done at first? I don't want to damage the finish, not get a screw locked in there, but nothing seems to screw in, not sure if its an issue with Aquatica housings in general or just mine.. 

I reached out to Aquatica on FB but they seem to take forever to reply.

 

(Sorry for the terrible phone pic)

Sorry to hear about this. I've never had a problem screwing the standard attachments to Aquatica housings, but I did need to re-tap one hole after it got damaged by galvanic corrosion.

It's pretty hard to tell from this picture, but on the farthest hole, which at least to me seems to be the clearest of the three on the picture, it kind of looks like there's some buildup in the threads, but it also almost looks like the outermost thread is cross-threaded.

If it's buildup you could carefully fill the hole with vinegar, let it sit for a bit and then soak it up with a napkin and use a hard plastic tip to carefully clean the threads.

If it's cross-threaded it can be fixed at home but there's a high risk of damaging the housing further so it would be a good idea to have it checked by whoever services housings in your area.

Thanks for your reply! I did just that, filled the holes with vinegar! Maybe I didn't wait long enough though.. Yeah, no one services housings in my area :)

What I might try is leaving vinegar in the holes for at least 4 hours and then giving it another shot, cheers!

Left vinegar in the holes for 5 hours, and then with a 1/4 screw with bigger grip for torque, I was able to slowly screw in and out back and forth, until the screw worked on all 3 threads.. cheers!

Are we sure that the threads are SAE and not metric? I have a D7000 Aquatica housing that packed away or I would check.

If your holes are now clean, pack them with o ring grease.

Sorry for the late response, I was away last week :)

 

The thread of the holes under all the Aquatica housings is 1/4-20
