Tee nuts and m6 bolts

So been switching a lot of drivers lately and having massive problems with the bolts and t nuts all the time. I dont know the exact english word for what happens, in short the bolts start spinning in place and then with the whole t nut . Is this supposed to happen  , i suppose its really bad quality materials of the tnut and m6s which make the windings easily damage .
Any links/guides for quality m6 and t-nuts in which these things wont happen? At least not as often.

I never used any glue for the t-nuts on my speakers.I usually drill the hole a bit smaller than the t-nut then knock it in place with a big hammer.I had one once that damaged the winding because i forced the bolt spining it in place,than it wony come off,insisting i had it turning in place damaging the entire wood arround it,luckly i managed to cut down the bolt and remove it.

Yes they wont spin in place when you screw them on,if you succeed screwing them on that is. But when you go to unscrew you feel that moment when the winding damages and the screw is done. Its annoying as hell and it happens way too often.

Actually lately used some hurricane nuts,they didnt fall out of the back like t nuts but still the m6 got its windings screwed and ended up spinning in place. What materials are not prone to this? Titanium,stainless steel? Only kind i can buy in my town is the kinda blue-ish type of metal.

i have found they're more troublesome in mdf than ply.

Sounds like you want to maybe drill the holes a little smaller so the wood grips the nut all round and really *really* get the fixing in the wood tight before you put any drivers in at all.

Like said use a chunky washer (or steel plate) and drive in a bolt to tighten it with an impact driver. If you don't have one then use an allen key and a bit of pipe to get proper torque on it.

They fall out cos if you do them only hand tight, well that's how tight you put the bolts in too. So when you undo them you get a 50/50 chance of the bolt undoing or the whole lot coming out. And even if the bolt comes out, you're still going to loosen the nut a little.
