I'm wondering what the proper name is for the bush that screws into
the bottom of the bulb holder in a table lamp? If I knew what they
were called, I might have a chance of searching for them.
I'm curious why they don't seem to be sold with the bulb holder or at
least why they aren't sold by the shops that also sell bulb holders. I
realise the DIY make-your-own-lamp market must be very small but there
must be some demand, and they must also be useful when the bush in a
shop-bought lamp breaks. Or is it just that we live in a throw away
world and they expect us to buy a new lamp when that happens?
I've always called them "lamp nipples". You can get them from
woodturning suppliers - e.g.
As I remember there's more than on thread combination around, but the
1/2" - 3/8 BSW is common. You can screw the coarse end into a 5/16 hole
in the wood but better to use a proper tap first.

Thanks. Typing "nipples" into ebay has found some results. I haven't
been brave enough to search using google!
Thanks. I'm actually after the sort for ceramic lamps, so I don't need
the woodscrew on the other end. I've found some described as "threaded
tube" or "all thread" which would suit my needs. It seems you can buy
it in various lengths.
I assume that if you bought a big piece you could cut it into shorter
lengths? And I assume that any old M10 or M13 (as appropriate) nut
I see there is also a plastic grommet to fit inside. Is this essential
or just desirable? There seem to be fewer people selling it, which
suggests the latter.
I needed one of these for a lamp that broke a few months back. This
time I want to replace a lamp with a screw fitting with a BC fitting.
Another problem I have run into is that most online sellers do not
state whether the lamp holder is threaded for use in table lamps and
if so, which thread they use.
I note that table lamps often use holders with integral switches and
these are rarer too.
