• 12-Point Box End: The 12-point configuration allows for fine indexing, making it much easier to connect with fasteners at twice as many angles compared to a 6-point wrench. It is highly versatile, fitting 4-, 6-, and 12-point fasteners.
• TorquePlus™ Drive System: The box end incorporates Proto’s high-performance TorquePlus™ system. This design shifts wrench contact away from the fastener corners and onto the flat sides, which minimizes rounding and allows you to apply efficient torque transfer safely.
• Full Polish Chrome: Forged from alloy steel, the entire wrench features a premium mirrored chrome plating that offers heavy corrosion resistance and wipes clean easily after greasy jobs.
