Thread: making detachable joins

Welcome schwartzberg!

How about screwing a long bolt into the threaded insert, adding a drop or two of thick CA glue to the insert's external threads and then inserting it into the hole.

When the glue has set, you can unscrew the bolt.

You could always use the Imperial equivelent (this would be my preference). You could also cut a piece from an "L" shaped allen key and put it into a socket and drive it with your standard socket set, or you could make an aligning jig enabling you to screw the insert in straight and accurately with an "L" shaped allen key.

Personally, I would'nt be looking for a different method of fixing, though a method of achieving what you want. Chances are you'll be wanting to do the same thing again at some stage in the future.

...i have never managed screwing a threaded insert straight ... using the allen wrench with a on a M4/M5 bolt screwed into the threaded insert and then applying/screwing the treaded insert with this (using glue or water on the external thread) ... well the allenwrench might give the balance in getting it in straight - for sure better than the Imperial Way ( == using a screw driver ... which has never worked for me ... my threaded inserts are something like 15-20 mm long making them impossible to be screwed in straight .. i think if they were longer or of a difffernt type the imperial way might fair better) ... also i notice doing it in soft pine wood is easier ... in the couple projects where i currently need it, am using hardwood (Walnut) which also became (a bit) brittle by the kiln drying process from where i bought the wood .. making the -- straight --screwing of short threaded inserts the Imperial Way nearly impossible.

... the bolt i use though cannot be deaper than the inserted thread.... i think though the T-tool (one for M4, another for M5, another for M6) is the way if i use threaded inserts since it is - one tool - and that alone in contact with threaded insert -- it makes the probability of sometimes threading it in crooked fairly limited - . i ... t h i n k !

Thanks..

...or i need to make these myself. I would be looking for more imput to this thread... i am pretty sure there must be a M4/M5 T tool out there somewhere.

Also ...sources for other fittings allowing detachable joins ... i mean where do the plethora of furniture manufacturers find these fittings !?

Thanks

Personally I detest those damned things.

I jave made a couple of beds that are fully demountable. I used long bolts and cross nuts.

You may have misunderstood what I meant Paul. When I said try the imperial equivelent, I meant the T wrench equivelent. for example, if you require a 3mm T wrench, but you can only get imperial, use a 1/8th T wrench instead.

Perhaps a jig to align your insert with the hole it is to go into .Jigs are an essential IMHO

will reply later with links and more from my own research into this.
It is more than just cross nuts. Also at the moment, this thread, is a top hit on a google search with the words "detachable joins for wood". Maybe google put a cookie on my machine that does that, it is otherwise amazing, or linquistic, ie., most other people/firms use other words for it.

Stuff i am loooking for are made by - for example - Hettig or Haefele.

There are more and i'll update this thread. But others are welcome too. Australia is at the center of things )
