These stainless steel cap screws are used to
replace the GM security bolts used on the Stage
2 style pulley system.  The security bolts require
a special bit for installation/removal and can
easily become stripped.  

The replacement cap screws use a common
6mm allen wrench which allows for much easier
installation/removal of the retaining hardware.
