Speaker Knurled Nuts
Posted 16 May 2011 - 08:49 PM
For those of you that own Larger Advents or AR speakers with the knurled thumb speaker nuts, read on.
I have taken a real blurry photo of new brass and older stainless steel knurled speaker wire nuts.
On the left moving to the right, is 6-32, 8-32 and 10-32 polished brass knurled thumb nuts, then 2
stainless steel from AR-2 speakers and lastly 2 stainless steel from a pair of Larger Advent speaker systems.
I bought the brass ones recently from Rona, a large home hardware store here in Vancouver, for less than $2.00 each.
The correct size for each speaker system is 8-32.
I cannot show better detail of the difference between the stainless steel ones.
To my eyes the stainless steel ones were machined by two different suppliers, not that it matters a whole lot in the big picture.
The new brass ones appear to be machined identical to the ones from the AR-2 speaker system.
I only wrote this for those of you that may need to replace missing nuts.
UPDATE: The .jpg file is 2.4 mb in size so it will not upload, oh well, it was not a great photo anyways.
UPDATE: Again tried different camera, file is much smaller, still blurry though.
UPDATE 20110526 Here is two other much better photos taken off the internet of the knurled nuts.
I did see a very small difference between the AR and Advent s/s nuts. The AR nuts were drilled out and chamfered just slightly.
The Advent nuts were sharply beveled, this would allow for less threading and less supporting threads.
I am really spliting hairs here but AR might have paid a few cents more per bag but bought a much better product, IMHO.
AR also had more solidly built speaker cabinets compared to the Heathkits, they likely cost them more money as well.

I bought some on Amazon a while back--the 8-32 for speakers and 6-32 for my KLH Model Eight radios--but they do not seem to be available now. They were about 40 cents each but you had to buy 100
btw--the brass ones are available in most hardware stores (even Home Despot) and I'm sure they are less than a buck apiece.
