KPMI® Cylinder Studs are made from 180,000 psi yield strength, 昀椀ne grain, heat treated, aircraft grade alloy steel. When you want a stud that meets proof-stress
and maximizes clamping force, look no further. KPMI® “rolls” the threads, heat treats and then centerless grinds the entire body of the stud. Rolling the threads
creates the toughest and strongest thread possible and centerless grinding removes notch sensitivity. The 昀椀nal process for all KPMI® Studs is to encase the
entire stud with premium corrosion resistant treatment of Black Oxide. Congratulations on your choice to purchase a stud that meets and exceeds your stockreplacement of high-performance needs!
