INITIAL FORM OF
RIVETS
• A riveted joint is a permanent joint which uses
rivets to fasten two materials .
• Structure that has a hemispherical head on
one side and a cyclindrical shaft on other.
• On installation the rivet is placed in a
punched or drilled hole, and the tail is `
upset, or bucked (i.e., deformed), so that it
expands to about 1.5 times the original shaft
diameter, holding the rivet in place
MATERIALS :
• Aluminium alloys , Steel , METALS like
titanium , nickel etc

4. RIVETED JOINTS
TYPES OF RIVET JOINTS :
BUTT JOINT
LAP JOINTS :
In this type the ends carrying the drillings of the
two members are positioned such that their
surfaces slightly overlap. The riveting is done
through the coincident holes .
BUTT JOINTS :
The two members or the elements are linked
edge to edge in one straight line . The clamping is
produced using an external cover plate which is
then riveted as above through the parallel drilled
holes .
LAP JOINT

5. RIVETED JOINTS
SINGLE RIVET JOINT :
One rivet is fixed along a single row typically
in a lap joint , while in a butt joint the rows
may appear from both the upper and the
lower surfaces .
DOUBLE RIVET JOINT :
When two rows of rivets are included over a lap
joint or when two rows of rivets are utilized from
both top and bottom in a butt joint are referred to
as double butt joint.
CHAIN RIVETED JOINT :
In this type the accommodated rows of rivets may
lie exactly opposite to each other over straight
lines .
Single Rivet butt Joint
Single Rivet Lap Joint
Double Rivet chain type lap Joint
Unlike the above type, here
the rows may appear staggered and not
complementing each other.
ZIG ZAG RIVETED JOINT :
Double Rivet zigzag type lap Joint
