General Mechanics Tool Kit (Item 1, App B)
Dissimilar metals should be avoided in attachments to minimize electrolysis. Cadmium plated fasteners shall not be
used unless absolutely necessary.
Two types of rivets are used in construction of this unit, Drive Rivets and Blind Pull-Thru Rivets. Both are generically
known as pop rivets and will be referred to as "appropriate rivets" in these procedures.
The Drive Rivet is used for repairs where only one side of the unit may be accessed. Drive Rivets have a hollow center
through which a pin is pulled expanding the diameter of the rivet. Drive Rivets are made of an aluminum alloy and is
formed with a domed head. It contains a headed stainless steel pin.
The second type of rivet used in the construction of this unit is the Blind Pull-Thru Rivet. As with the drive rivet, this
rivet is used when only one side of the part being joined can be accessed. It is a hollow rivet which contains a pin which
expands the rivet as it is pulled through. Like the Drive Rivet, the body of this rivet is made of aluminum, however the
center pin is also made of aluminum. This type of rivet is used where one of the pieces being attached is made of
stainless steel. Because rivet is made of aluminum, it will not cause an electrolytic reaction with the stainless steel
