66 THE DISTRIBUTOR’S LINK MEMORIAL TO BENGT BLENDULF by Laurence Claus In June of 1991 I was a young engineer, perhaps four years into my career in the fastener industry. I was filled with anticipation as I stepped into the Sheraton Hopkins Airport Hotel Ballroom to attend my first formal fastener education on Fastening Technology sponsored by Clemson University’s Office of Professional Development. Although I didn’t know it at the time, I would be introduced to a virtual Who’s Who of the fastener industry such as Richard Barrett of NASA, Craig Hood, Ralph Shoberg, and Charlie Wilson. Leading the group and the originator of the conference, however, was Bengt Blendulf. In June of 1991, the industry was wrestling with how the newly enacted Fastener Quality Act would impact it and I recall Bengt beginning the session with an impassioned presentation on “Mechanical Fasteners are Engineered Components, Not Just Simple Commodity Items” which would set the stage for the next two days. Although Bengt was on the faculty of Clemson University at the time, it was immediately obvious that he was not your typical, overly academic professor. No, Bengt was a dynamic presence that lit up the room with his passion, knowledge, and stories which illuminated this topic in a way most people are unable to do. In fact, Joe Greenslade, another of the fastener industry icons, would once say of Bengt, “From the first time we met it was obvious to me that he was one of the brilliant minds in the field of fastener technology. Bengt is one of those rare individuals who can explain technically complicated subjects in terms that can be comprehended by his audience regardless of their educational background.” This was my first introduction to Bengt and, although, for many years I would only know him as one of the instructors, I would always have a point of reference anytime I would see his name as a highlighted speaker or author. It was a great honor, therefore, when Joe Greenslade called me one day about six years ago and asked if he could introduce me to Bengt. Since I had started teaching about fastener related topics he thought the connection with Bengt could be helpful. That simple act of kindness on Joe’s part would put Bengt and I together and rekindle that first connection from long ago. Bengt invited me to sit in on several of his classes and I, once again, got to see him in action. He once described his classroom approach as “dynamic” and one in which participants will not fall asleep. That description was very appropriate and Bengt had a wonderful way of weaving stories and wit into his teaching. As much as I appreciated these opportunities to sit in on his classes, I think I appreciated even more the time spent with him after class. Not only would he share advice and knowledge but he talked a lot about his family and his two very talented daughters, so that our relationship transformed from instructor and student to a friendship. Bengt was trained in Sweden as a mechanical engineer and would begin his near lifelong career journey in the fastener industry in 1966 with fastener manufacturer, Bulten. In 1974 he would come to the United States to open a subsidiary for them. He worked in manufacturing until 1988 when he joined the faculty of Clemson University’s College of Engineering and Science. He would remain with Clemson for eight years, departing in 1996 to found EduPro US Inc., where he was President and Principal Lecturer until his retirement at age 80 at the end of 2018.

THE DISTRIBUTOR’S LINK 67 BENGT BLENDULF RECEIVING THE IFI SOARING EAGLE AWARD FOR SIGNIFICANT CONTRIBUTIONS TO THE TECHNICAL ADVANCEMENT OF THE FASTENER INDUSTRY Through most of his career, Bengt possessed a strong focus on educating fastener users and those coming up in the industry on a topic, Fastener Technology, that he knew does not garner enough attention in universities and colleges. He felt, however, that the subject should be taught in a practical way so that the average user could understand and apply good practice in the real world. He perhaps summed up this philosophy best in an interview he did for Fastener Industry News in 1995 when he explained something he had learned during his time in the Swedish Army. He said, “When a map and terrain do not coincide, chose the terrain.” He would explain that if a fastener were perfectly designed and manufactured, it still would not guarantee that it would properly perform on the job and that practical matters had to be considered. Intertwined with his many other activities, Bengt was one of the founding members of the Bolting Technology Council and would hold its chairmanship from 1996 to 2006. The Bolting Technology Council was originally formed as an independent organization of engineers dedicated to the art and science of threaded fasteners. The bolting Technology Council continues the good work started by Bengt and the other founding members today as part of ASTM’s F16 Fastener Committee. In addition to this council, Bengt exhibited a lifelong commitment to bettering fastener standardization, especially metric fastener standards, for which he would receive the Fred F. Weingruber Award from ASTM in 1996. In 2013, Bengt would go on to become one of a very elite fraternity to hold both this award and the Industrial Fasteners Institute Soaring Eagle Award for his significant contributions to technical advancement of the fastener industry. Bengt was a consummate writer, over the course of his career authoring or coauthoring over 100 journal articles and several books, including “Joint Technology for Threaded Fasteners”, “Mechanical Fastening and Joining” and contributing to “Handbook of Bolts and Bolted Joints”. Sadly, Bengt passed away on April 22, 2020 from his on-going battle with Stage IV Glioblastoma. According to his daughter, Jessica, he “left us peacefully on Earth Day”. It was truly an honor and a privilege to have known and been able to work with Bengt. I will miss him but am comforted in knowing that his legacy to the fastener industry and all who knew him will endure for a long time to come. LAURENCE CLAUS
