Using T-Nuts to mount a sub...

[riored4v 8]

Just wondering what size to go with?  When I ordered from Parts Express, the guy on the phone recommended 1/4" x 20, but turns out these dont fit the opening in my IDQ sub.  What size does everyone else use?

what about 10-32

I think I got mine at lowes or orchard supply.

Makes me wonder if the openings are smaller on the ID sub than others. That's the same size I currently have.

I always use 10-32 or 10-24.  No need for anything larger.  I like to steer away from the brass inserts myself as they are too soft IMO.  I prefer steel with an allen insert as well.  The flat blade inserts are too easily stripped.

Are these any good???

I am sorry, it not absolutely that is necessary for me. There are other variants?

Spam?

The made you do not turn back. That is made, is made.

I'll look for those at HD and see how much smaller they are than the 1/4.

 

My other though was to just mount my ID sub using wood screws and once my other sub gets here, to just open the holes up and use the inserts/t-nuts at that point.

[riored4v 8]

Also need some opinion on what I should do here.  My box design would allow for basically 6 of the 8 t-nuts to be used.

 

I obviously can't get behind the surface of the top and bottom mounting locations, so I was wondering if i can put the inserts in from the top with some wood glue and let the "teeth" bite the surface of the wood rather than the backside?  Would this work at all?  Or should i use wood screws for the top and bottom?

For the top and bottom you'll have to use regular screws, or something like those threaded inserts that Shogen posted.  The T Nuts have zero hold used the way you described.

 

 

I'm going to have the same issue with my enclosure.

[riored4v 8]

Kind of what I assumed, but figured I should double check. Not really a fan of having 2 woodscrews and then 6 allen head screws. Since I'm going to have to buy a new of screws anyways, would it be best to just use inserts all around? 

 

Side note... Alton, the box you designed for me fits perfect.  Hits all my old mounting locations of the previous box.  Thanks again!

Yeah, I'm looking for something to make it kosher all the way around myself.

 

I have found these, not sure how well they would work, but this is the type of thing I'm looking at using just for the top and bottom screws on mine.

[riored4v 8]

Those look pretty nice.  Wonder if I can find something like that at Lowe's for a wood application.

Those are very similar to what I use. I get mine from McMaster Carr.

one way that MIGHT work is turning the sub so u avoid that surface, may not be ideal for what u want but it might work

I had considered that too.  But I'm pretty anal with the aesthetic stuff, and having a crooked sub would REALLY bother me.
