Help needed to identify speaker connector size...

[ellal]

A couple of the plastic screw caps have broken off a pair of speakers. I usually just connect the cable bare via the screw cap and slot.

How do I determine the guage of the screwtop, or were I to go down the 'banana' connector route is the size I would need the internal dimension of the existing connector as shown below?
I'd prefer not to dismantle the back of the speaker, but so far I haven't found anywhere that stocks just the caps. Gone are the days of popping down to maplins!

Cheers

AFAIK banana plugs are a standard 4mm.

you can get screw in ones for the speaker cable so they dont need soldering

like these ones for eg:

you can get elbow ones if access is awkward

Ellal,
You could look here for a similar "speaker binding post", buy the cheapest, and just use top screw down section. My gut feel from using these a lot in Labs and on speakers that they are all about the same.
You would need to cross your fingers that they are the same size, but might be worth the try for £3.

I had seen 6mm ones advertised, but maybe that is max cable size?

I was hoping to carry on using the stripped cable/screw cap method something like below, but not sure if thread is universal - it doesn't look like it is.

As in my reply above, the threads look different.

Thanks for helping expand my search term words, as I didn't know they were called 'binding posts'.

You are probably right as the ones on your Speakers also look like a captive thread, in that the thread does not go all the way to the top to stop the caps from being fully unscrewed.

For all the speakers and lab gear that I use, I buy and use "4mm Banana plugs".

I'm probably going to have to 'bite the banana' and change my connection method then...lol
(I'm assuming that the screw cap isn't required to 'anchor' the banana connector?)

I have some chrome plated binding posts from Monitor Audio that look very similar to yours. The caps aren't removable though.

Ellal,
Banana connectors are friction held in the hole, the screw cap is not needed.
Banana connectors can go into the top hole or side hole (which you used for cable) - Although in your photo the side hole looks a bit obscured by the mounting nut.

Thanks for all the replies.
Have just ordered a set of banana plugs.
