46 THE DISTRIBUTOR’S LINK 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 01832; phone and fax 978-521-0277; e-mail: 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. CONTRIBUTOR ARTICLE 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.
