ASI-250 : ASI-500 : ASI-562 : Super-Stud™ Stud Installers (Discontinued sizes)
Installing studs just got easier! Each installer is size-stamped for easy identification and include a steel ball inside to prevent over-tightening of studs. To install studs, simply install the stud into the correct size installer; hand-set the stud into the cylinder head then use a standard 3/4" wrench or stocket to tighten the stud into place. Perfect for high-performance.
