__TOC__

=====Description=====
[https://en.wikipedia.org/wiki/Rivet '''Rivets'''] ''(aka Rivits)'' have various designs of head at one end and are used to fasten materials together by being passed through a punched or drilled hole and hammered over ''(usually)'' to form a head on the reverse side. They are available in several materials and sizes, can be solid or hollow and specialised designs also exist ''(e.g. ‘Pop’ Rivets).

=====Rivetting Process=====

# '''Rivets''' are first passed through the punched or drilled holes then, with head supported on a hard surface, a hollow tool with a hole equal to the '''Rivet''' diameter is struck down over it to squeeze, or '''Set''', the pieces of material together
# The tool, or '''Rivet Set''', is removed and using a hammer, the '''Rivet''' is first struck [[Squareness|square on]] to thicken it inside the holes
# The the head is formed by hammering over.
# The completed rivetted joint.
----
<span style="color: green">'''Note:'''
Where several '''Rivets''' are to be used to form a joint, it is important to drill through both parts just once initally, and this hole rivetted before drilling through and rivetting any further holes. This is because it is most unlikely that drilling separately would position the holes accurately enough.
