Although I am no longer in art handling, i have never liked t-nuts because
they often fall out.  many of the bolt-plated crates that i have handled over
the years have not been very impressive either, although they do seem to hold
up better that t-nuts.  on the other hand, we used to use( i don't know if
they still do) a threaded insert which was actually screwed into the frame of
the crate and the lid bolts threaded into those.  they were quite nice as i
recall and rarely got lost. although, they could get torn up when an over
zealous 'art handler' would try to hammer an off kilter bolt into position.

just my thoughts on the subject

PLEASE RESPOND
I work for a firm that involved heavily in the crating, packing and
transport of artwork. It has been brought to my attention that more than a
few art instittutions have a preference of the "bolt plate crate" over the
"t-nut crate". I do have my personal opinion and arguments for which one I
am sure is superior but I, we (my coworkers and myself) are curious what
curators and others involved in art handling and shipping feel about this.

Please e-mail at the following address and i will respond back.
