Controlled hexagon for maximum wrenching strength. Smooth fillet radius to withstand head soundness. Formed threads with improved root radius provide greater strength to threads. Uniform & uninterrupted grain flow for greater strength. Controlled mechanical properties for higher strength. High quality steel for good strength & wear resistance. Controlled Concentricity in totality helps to create a high resistance to lateral movements.
