GripEdge Patented RPT geometry delivers up to 50% more grip on new fasteners and up to 400% more grip on damaged fasteners vs standard tools 
• RPT Hex geometry is engineered to replace conventional tools by preventing the rounding of good fasteners and effectively removing damaged ones 
• Low-profile dual-action drivers measure just 1-1/16” (27mm) in length, while maintaining a full-length tip across most sizes to ensure complete contact inside fasteners 
• Multiple drive options: 3/8” internal square and 17mm external hex 
• Large laser etched size markings for greater visibility 
• One-piece S2 steel construction for increased strength and durability 
• The kit includes sizes 1/4, 5/16, 3/8, 7/16, 1/2 & 9/16"
