Types of rivets
Solid rivets
Solid
rivets are one of the oldest and most reliable types of fasteners. Solid rivets
consist simply of a shaft and head which are deformed with a hammer or rivet
gun. The use of a rivet compression or crimping tool can also be used to deform
this type of rivet; this tool is mainly used on rivets close to the edge of the
fastened material, since the tool is limited by the depth of its frame.
The setting of these fasteners requires access to both sides of a structure.
Solid rivets are driven using a hydraulically, pneumatically, or electromagnetically
driven squeezing tool or even a handheld hammer.
Blind rivets
Blind
rivets, commonly referred to as pop rivets, are tubular and are supplied with a
mandrel through the center. The rivet assembly is inserted into a hole drilled
through the parts to be joined and a specially designed tool is used to draw
the mandrel into the rivet.
Unlike solid rivets, blind rivets can be inserted and fully installed in a joint
from only one side of a part or structure, "blind" to the opposite
side.

Lap joint: A joint formed when two surfaces overlap one another. Lap joints provide more stress resistance than butt joints.
Butt joint: A joint formed by two surfaces that meet without overlap or complex intersection. Butt joints are often combined with other joint designs.
