This is the difference between a GripEdge RPT Hex and a standard Hex tool. Our GripEdge RPT Hex has Rounding Prevention Technology (RPT), which prevents damage from happening to Hex fasteners. They are a complete replacement for your standard Hex sets; use them on brand new fasteners and get up to 50% more Grip, and when used on damaged fasteners, get up to 400% more Grip. #enginerepair #automotiverepair #HandTools #gripedge #mechanic | GripEdge Tools

The standard Hex tool rounded out the 3/16 Hex set screw. Gripedge RPT hex prevents damage from happening to fasteners and is a complete replacement for your standard tools. #mechanic #toolsforsuccess #handtools #enginerepair #technician | GripEdge Tools
