Hurricane Nut (T-Nut) Evaluation

[David_D]

That is also a fine plan Steve.
I would think you may have some challages trying to get them close enough the speaker cut out, but one could also tap those holes off center to the nut. If I was going to attempt this I would probably choose aluminum. In case one of the nuts gets nicked while trying to bevel the inside of the speaker cut out. My job requires me to use alot of aluminum and I use a standard wood router & bit to put chamfers and round overs on aluminum pieces, so I know standard carbide cutters can easily handle cutting the aluminum.
Honestly, it sounds like a lot of work.
Good luck - let us know.

Bump.

Just thought I'd bump this as a great piece of DIY info. Ive been talking to people lately about driver attachment and t-nut installation and I'm always searching up and referencing this thread. Thought I'd drag it back up to the top for a minute for all the new guys that never got to see it when it was made.

Threaded insert nuts. Love them!
After using hurricane nuts, t-nuts and losing my nuts after even epoxying them in, I went to a woodworkers shop and found these.
Try them out.

Did you forget to include your link? I googled threaded insert nuts and got all kinds of different results.

You can see them in place here. The ones i used are the ones with the flange on top. You can use them from the front or the back. I chose the front in case i ever had any problems i could remove them easily.

all sorts of different lengths and sizes. I did use them with cap head bolts though. They will work with 1/4-20 mochine bolts too.

+1 on Mike's suggestion (and Dan N before that) to use threaded insert nuts. In fact David D could fix those two loose screws with a couple of inserts. I had a project where the hurricane nuts (actually called "propeller nuts" at the local hardware store) kept spinning out because I had the bolt circle diameter a little off, and the bolts were going in with an angle and cross threading. I ended up pushing all the hurricane nuts out and turning them around backwards, pinching them with my fingers while tightening the bolts (this was an open baffle). Worked fine that way but obviously not possible with a typical box. Must admit that the threaded inserts would not have helped my error with the circle diameter. ops:

I think most people who use any of these items fail to understand how important it is to have them sitting as straight as possible and lined up properly to the bolt that is being used. If whatever you are using isn't sitting straight or is not lined up properly to the bolt it will pull to one side and unseat it. For the majority who are using mdf it cant withstand this and breaks apart or strips easily.

I used H nuts on my Tempest Sonosub - installed with epoxy - worked fine. However, now when I need an internal thread, I'm with Dan on this:

I never cared for t-nuts and prefer to use threaded inserts like these:

I use the T-nuts with a good dose from a hot glue stick, and hammer the little buggers in. Just be careful not to get any glue in the threads.

I use drywall screws, wood screws, and kreg screws. no nuts. :P

Just to cause trouble: since I've been using just screws, I haven't had problems. I have stripped out a hole or two, I'm sure. But when I do, it is easy to get the screw out of the hole. And before I put the screw back in, I just put a little glue on a wood match stick, stick it in the hole, let it sit for a minute or two, then drill the screw it. Works great. I think someone here told me that trick.

I just don't see the need for fancy nuts, except for macadamia nuts.

Easy there MacGyver. :B :B
