52 THE DISTRIBUTOR’S

52 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: tdimaio@verizon.net. SELECTING THE CORRECT BLIND RIVET The following consideration should be given when selecting a blind rivet for your application. [1] Tensile And Shear Values The blind rivet must have the proper tensile and shear values to fasten the components of your blind rivet application. Whatever the required tensile and shear strengths needed to properly secure the riveted joints plus substantial safety factor, blind rivets wide range of tensile and shear values will satisfy the requirements. Break Mandrel blind rivets have a tensile range of 75 to 2100 pounds and a shear ranges of 50 to 1700 pounds for one blind rivet depending on size and alloy. Therefore, step one is to establish the necessary or desired tensile and shear values for the blind rivet application. Blind rivets are also produced with higher shear values above the Break Mandrel design and these blind rivets are called Structural blind rivets. Structural blind rivets have a shear value up to 2400 pounds. Step No. 1 is establishing the correct tensile and shear values for your blind rivet application. [2] Alloy The next selection to be considered is the alloy of the blind rivet. Blind rivets are produced from the following alloys and alloy combinations. RIVET BODY MATERIAL Aluminum Aluminum Copper CONTRIBUTOR ARTICLE MANDREL MATERIAL Aluminum Carbon Steel Carbon Steel RIVET BODY MATERIAL MANDREL MATERIAL Aluminum Stainless Steel Steel Carbon Steel Monel Carbon Steel Stainless Steel Carbon Steel Stainless Steel Stainless Steel What atmosphere will your blind rivet application be subjected to, is a factor that must be considered. If the outside is where your application will be subjected to, than the alloy of the blind rivet should be aluminum rivet body and aluminum mandrel or stainless steel rivet body and stainless steel mandrel. Many times I have been asked, "can I use an aluminum rivet body with a steel mandrel or a stainless steel rivet body with a steel mandrel?” My answer is, that even if the blind rivet mandrel is plated, you should not use a steel mandrel in an outside atmosphere because when you break the mandrel setting the blind rivet, where the mandrel breaks the steel is now exposed to the atmosphere and will rust. This rust will appear at the flange side of the set blind rivet. Blind rivets with a steel mandrel should not be use in outside atmosphere. If your blind rivet application is subjected to food, such as in slicing machines or on counters or food worktables, stainless steel rivet bodies and stainless steel blind rivet mandrels should be used in the blind rivet application. In this blind rivet application blind rivets with steel mandrels should not be used. Blind rivet applications that are not exposed to the atmosphere or food, anyone of the blind rivets alloys shown in the above chart can be used. CONTINUED ON PAGE 130
