Document Summary
Relies on mechanical interlock of di erent parts to achieve fastening. Discrete: uses an external element for fastening (bolts, nails, staples, rivets, thread) Intrinsic/integral: designed internal to the workpiece so no external elements are needed (snaps,crimping points) Use standard parts and as few parts as possible. Keep holes far from edges to prevent tearing. Generally, they are cheaper and easier to use than discrete fasteners. Mechanical fastening has the advantage that it can produce joints that can be assembled and disassembled. Something that none of the previous processes described can do. This feature is useful for assemblies that require future access for maintenance, for example. Seams are used to close and seal sheet metal products. An example of such seals is the top of a soda can where the lid is joined with the body. That seal can prevent leakage and maintain the pressure of carbonation in the can.
