I am building a large table and want to reinforce the legs/aprons with metal
corner braces (there isn't room for wood).

They all show attaching to the legs with hanger bolts. That seems like a
lot of trouble; why not just use screws? I will never (hopefully) be taking
it apart, which seems to be the only reason for the hanger bolts.

But, it is my first big table and maybe there is a good reason I am not
seeing. Thanks.
