Anthony Di Maio
Anthony E. Di Maio attended Wentworth Institute and Northeastern University. In 1962 he
started working with Blind Fasteners as Vice-President of Engineering & Manufacturing for two
blind rivet manufacturers. He has been Chairman of the Technical Committee of the Industrial
Fasteners Institute (IFI) and is still involved in the writing of IFI specifications. In 1991, he
started ADM Engineering and is working with Fastener Manufacturers developing new fasteners
and special machinery. He can be reached at ADM Engineering, 6 Hermon Ave., Haverhill, MA

BLIND RIVETS SHEAR & TENSILE VALUES
A set blind rivet offers resistance against shear &
tensile forces applied to the riveted assembly.
Shear and tensile values are important when selecting
a blind rivet for an application. The user wants their
assembly application to have a secure and permanent
assembly. Blind rivet manufactures list the shear and
tensile strengths of their blind rivets. Knowing the shear
and tensile strengths that will be applied to the riveted
assembly, a user can select a blind rivet that will have
the shear and tensile values that will exceed the forces
applied to the riveted assembly.
There are two types of blind rivets, standard “openend”
blind rivets and “structural” blind rivets.
“Open-End” Blind Rivets
Standard
Tensile
Shear
Aside from the different diameters that offer a range
of shear and tensile values, you also have a range of
materials that each offer higher shear and tensile values.
A blind rivet can be made that will function well in the
application but also the selection of the material of the
blind rivet that will satisfy the environment that the blind
rivet will be subjected to.
“Structural” Blind Rivets
Structural
Standard
“Open-end” blind rivets are manufactured in the
following diameters 3/32, 1/8, 5/32, 3/16 & 1/4 and
are made of aluminum, steel, and stainless steel. Each
of the diameters and each of the different materials offer
different shear and tensile values. The larger the rivet
diameter the higher are the shear and tensile values. A
user has a very large range of shear and tensile values to
choose from that will more than satisfy the assembly of
their components.

Structural
There are many types and alloys of structural blind
rivets available that offer very high values of shear and
tensile that will work well in very high shear and tensile
requirements.
