RIVETS
A rivet is a permanent mechanical fastener. Before being installed, a rivet
consists of a smooth cylindrical shaft with a head on one end.
It is a permanent joint which mean that it cannot be disassembled
without failure of machine component.
This joint form interference fit to joining the parts. Rivets apply
mechanical force on the two plates which joint the plates permanently.

The process by which two plates are joints together by use of rivet is called
riveting.
In this process mechanical force is applied to make the joint strong and
leak proof. In this operation two holes are created in both plates and the
rivet is inserted between these holes.
At the other end a force is applied through a die which deform the tail
plastically and form a required shapes which hold the rivet in the hole and
apply a mechanical pressure force which joint the structure.
This process is shown by figure.

RIVETS JOINTS
1- LAP JOINT :
When the plates to be joint, are bring together which overlap each other
at face, and rivet inserted in overlap section as shown in figure, the joint
is known as lap joint.
According to the number of rows of rivets and its arrangement, this joint
is further classified as follow

RIVETS JOINTS
1- LAP JOINT :
A- single riveted lap joint: In this joint, the rivets are inserted in the single
line, that's why it is called as single riveted lap joint.
B- double riveted lap joint: In this joint, the rivets are inserted in the
double line, that's why it is called as double riveted lap joint.
C- Zig-Zag riveted lap joint: In this joint, the rivets are inserted in the
zig-zag line, that's why it is called as Zig-Zag riveted lap joint.

2- BUT JOINT :
In this type of rivet joint both plates are bring together without overlap
each other and joint are made by use of one or two cover plate.
End to end joint is known as BUT JOINT.
According to cover plates, number of rows of rivets and arrangement,
this joint is classified as follow.

2- BUT JOINT :
A- Single straps butt joint: In this joints, there is only one cover plate
used so it is known as single strap butt joint.
B-Double straps butt joint: In this joint cover plates are used both side of
the work piece, so it is known as double straps butt joint.
