Note the part number (AA-567) and type number (241) on the bottle. I buy this adhesive for about $6/bottle at Fastenal. I have seen it for sale online too. Be sure to wear gloves while handling this glue. Unlike regular cyanoacrylate adhesives this stuff does not soften in water. I use a 60 grit sandpaper to give the plastic sufaces a little bit of tooth.
These are better than the ones I bought on eBay that were actually more expensive! The eBay ones were "coated" and ended up rusting. These are encased in plastic and will last forever!!!
I attached them to eggcrate last night to make a frag rack. Thanks again!
