Clearing out more hardware. I have 3/4" brass nuts and washers, and a set of four 3/4" black steel top caps for building a rack. Not shown in photos: I also have a set of 32 3/4" black steel nuts.


These parts are leftover from a rack I built:
http://www.audiocircle.com/index.php?action=gallery;area=browse;album=3741Prices: $1.25 for each brass nut, 60 cents for each brass washer. $32 for the set of four black top caps. 25 cents each for black steel nut.
FWIW, more brass nuts and brass washers are available on eBay, as is 3/4" threaded rod.
