72 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: THE FASTENING POWER OF BLIND RIVETS The fastening power is the most important factor when selecting a fastener for your application. Your fastener selection must have the shear and tensile values great enough to offset all forces your assembled application that will be subjected to in all conditions. You’re fastener selections must always be positioned in such a way so as to offer it’s maximum shear and tensile values. If your fastener selection is a threaded fastener, you must be sure that the threaded fastener is tightened to the proper torque to give your application the maximum shear and tensile values. Blind rivets have the following built in benefits in it’s design and performance. Ease Of Setting Operation Blind rivets are a two piece fastener having a rivet body and a mandrel. Body .062 Max Mandrel Shear And Tensile The set blind rivet is now offering the manufacturers listed shear and tensile values. The rivet body has been designed to upset when the mandrel is pulled by the blind rivet setting tool. The rivet body material is according to the Industrial Fastener Institute (IFI) and is formed and heat treated to give the (IFI) listed shear and tensile values. Open-End blind rivets specification IFI-114 have 5 different diameters, 3/32, 1/8, 5/32, 3/16 and 1/4 and are produced in 12 different alley combinations listed with the rivet body and mandrel materials as shown in the IFI-114 specification. Shear Plane “A” Tensile After Setting Setting a blind rivet, you would insert the mandrel in a setting tool. The setting tool will pull the mandrel until it breaks at it’s tensile breaking point. The blind rivet is now properly set. The operator does not control when the mandrel breaks and also has no affect regarding the shear and tensile value of the set blind rivet.
