2024 ARP Catalog

12 Manufacturing high performance and race fasteners is very different from making commercial fasteners. As you read further into this catalog, you will get a better idea of the extraordinary steps taken by ARP to produce the strongest, most reliable fasteners of their kind on the market today. The foundations of ARP’s fastener technology were laid by founder Gary Holzapfel, President Mike Holzapfel and engineers Russell Sherman, P.E. and Dr. Kenneth Foster. This team used their vast experience in fastener manufacturing and design, metallurgy, mechanical engineering and stress analysis to create fasteners that suited the unique needs of racers in every form of racing. Building on this foundation, ARP worked with racing industry legends like Carroll Smith and Smokey Yunick to bring direct input from the racer’s perspective. As ARP’s involvement with professional race teams increased dramatically, the feedback loop drove continuous innovation in all of the fasteners ARP designs and manufactures. ARP has channeled those five decades of knowledge to continuously improve existing fasteners and kits, as well as create new ones for everything from diesel trucks to personal watercraft to the fastest land speed vehicles in the world. ARP has worked with Robert Logsdon to improve its quality control systems and create a culture of continuous improvement. He brought to ARP decades of experience in the areas of Metrology, Quality Control, Manufacturing, Acquisition and Configuration Management. Logsdon is a graduate of the U.S. Naval Academy of Metrology Engineering, the Defense Management College and U.S. Air Force Institute of Technology. Additionally, ARP has one of the industry’s most complete in-house R&D/QC facilities and a wide variety Robert Logsdon Q.C. Consultant Behind The Scenes A series of special checking devices are employed to monitor the quality of threads. For every thread size, there is a checking device. Two computer-controlled Instron tensile machines are used to determine the ultimate tensile strength of studs and bolts. THE COMPANY
