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!

Replacement nuts for Stud Kit, #82-83500, but can be used for general purpose (see diagram for detail)
These nuts are manufactured from a high strength premium steel that promotes excellent surface 昀椀nish and tight tolerances, two critical factors for achieving
correct 昀椀t and torque. After machining, the nuts are heat treated to a speci昀椀c depth. This creates hard, wear resistant working surfaces, while retaining a ductile
core to prevent cracking under load. The premium black oxide treatment gives an excellent, corrosion resistant appearance.
