A Ferrule or NOT a Ferrule, That is the Question?

[squidgelet10]

Greetings each.
I am trying to get my hands on some of those screw-threaded metal inserts ie inserts which screw into a pre-drilled hole in a piece of wood, but also have a female thread inside which allows another piece of wood to be bolted onto it. Does that make sense?
I call them ferrules but cannot seem to Google 'em!
Does anyone happen to know the correct name for these things, and also where I can buy them in UK please?
Many thanks.
Be good!
Cheers.

I know what you mean, but likewise, don't know what they are called. What about an old fashioned ironmongers?

This is the dictionary definition, does it make sense? http://dictionary.reference.com/browse/ferrule

There are lots of ferrules on eBay but they seem to be mostly for bikes?

The word ferrule derives form the Latin Viriola, meaning a bracelet. It has come to mean a metal band, especially one which strengthens an existing structure. The round knobbly things at the end of umbrella spokes are called ferrules. Just some useless information.

Hi,
Came in late on this one, but no one mentioned " helicoil springs" they did that job, people used them when they crossed threaded spark plug bores.
