Not likely...that site is for "antique" fastners.

How is this fastner so special for your chest.

Six months ago I saw a fastener somewhere, but now I have forgotten
where, and I can't find it.

It is a plastic, surface mounted, knock down corner connector for
panels. It looks a lot like the bracket on this page, (third down)

but it differed in that it had an outer sleeve that bonded the two
together, instead of the small bolt in this one.

"no tools required" is sounding good for my chest design.

Help! has anyone seen it?
