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 stock-replacement of high-performance needs!

Replacement nuts for Stud Kits, #60-61300, 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.

• By utilizing FEA software, it was possible to take advantage of the increased strength and wear resistance of a heat treated steel retainer, while reducing its
mass to within grams of a comparable titanium retainer
• KPMI® has gone a step further and speci昀椀ed the latest in spring materials and processing, for an extremely robust design that will last longer than anything
currently on the market
• Unique features of this spring include a beehive variable rate wind to reduce the chances of spring surge due to cam harmonics, Super-Clean Chrome Silicon
wire with additional Vanadium and Nickel added for increased strenth, and a gas nitrided and double shot peened 昀椀nish for greater fatigue life
