•GRIPEDGE R.P.T. (Rounding Prevention Technology) E-Star sockets are designed to replaced standard E-Star tools. R.P.T. prevents the rounding of good fasteners whilst being able to remove extremely compromised fasteners. 
•The unique, patented & Bi-directional geometry delivers up 50% more prevention torque on good fasteners vs standard tools, whilst applying up to 400% more torque on damaged fasteners vs standard tools. 
•Compromised fasteners can be re-inserted in a pinch if a suitable replacement is not available. 
•Each socket is forged from Cr-Mo steel for increased strength and durability as well as coated for increased corrosion resistance. 
•All sockets have oversize, roll stamped, and ink filled size markings for greater visibility and a nickel chrome plating ensures corrosion resistance. 
•Replaces standard E-Star tools
