• 6-Point Box End: Unlike the highly common 12-point version, the 6-point layout provides absolute surface contact on the flat walls of a 1/4" hex fastener. This configuration drastically lowers the risk of slipping, making it perfect for dealing with frozen, rusted, or soft-metal hardware.
• TorquePlus™ Drive Geometry: The box end is integrated with Proto’s advanced TorquePlus™ system, which applies force away from the sharp, delicate corners of the bolt and redistributes it across a wider surface area.
• Full Polish Chrome: Forged from premium high-alloy steel, the mirror-finish plating offers heavy corrosion and chemical resistance. The surface easily wipes clean of grease, oil, and grime.
• 15-Degree Offset Angle: The box head sits at a 15-degree angle relative to the shank, providing crucial finger and knuckle clearance when executing tasks flush against machine faces.
