Final answer:
Thread joints and rivet joints are both permanent joints that do not use adhesives and are not designed to be readily disassembled.
Step-by-step explanation:
The similarities between thread joint and rivet joint are that both are permanent joints used in various construction and manufacturing processes. Although they have different methods of assembly and applications, their primary function is to join two or more elements together in a secure and enduring manner. Thread joints typically involve the use of screws with threads that twist into materials or matching threaded holes, while rivet joints use a rivet which is inserted through pre-made holes of the parts to be joined and then deformed to hold the parts together without the need for threads. Neither of them require adhesives, and once assembled, they are not meant to be readily taken apart without potentially damaging the joined parts.
