The Stanley Proto 1/4-Inch Drive 5mm 12-Point Socket is engineered from high-performance, heat-treated steel for exceptional durability and long service life. Designed for use with standard 1/4-inch drive ratchets and extensions, it delivers maximum torque to quickly break loose rusted and frozen fasteners with less effort.
Featuring the patented SureGrip® hex design, this socket grips fastener faces rather than corners to reduce rounding and slippage — making it a reliable choice for professional mechanics, MRO technicians, and industrial maintenance applications.
