Key Features

• 12-Point Box End: The 12-point design allows for fine indexing, improving engagement speed and access in confined spaces, and is compatible with 4, 6, and 12-point fasteners. Box ends also provide more contact with the fastener, enabling greater torque transmission and reducing the likelihood of slippage compared to open-end wrenches.
• Standard 15° Offset: Engineered with a standard 15-degree offset, this wrench provides crucial knuckle clearance, enhancing user comfort and accessibility in tight work areas.
• Satin Finish: A non-slip satin finish offers enhanced corrosion resistance and a secure grip, even in oily or greasy conditions typical of professional workshops.
• Professional-Grade Construction: Manufactured from special heat-treated alloy steel, the wrench ensures superior strength and long-term durability, meeting the rigorous demands of industrial and automotive maintenance.
• TorquePlus™ System: The box ends incorporate the TorquePlus™ system, which helps reduce fastener rounding and allows for more efficient torque transfer.
