In order to maintain the essential friction fit when bolts are forced
into a bore, grooved pins, a form of
non-threaded fastener, are utilized. In applications with low end loads, these
are frequently utilized as locking mechanisms, pivots, bearing faces, or
locating components. Numerous different groove types are available for them.
These come in a variety of finishes and have had heat treatments to make them
more shear resistant. The procedure of swaging is used to carve the grooves on
these grooved pins.
