Proto 1/4Drive 12PT HUJ Socket 3/8 J4773AS-SBD

Proto's professional-grade 1/4-inch Drive 3/8-inch 12-Point Intermediate Universal Socket, precision-engineered for aerospace and high-performance industrial applications. This specialized tool features a universal joint for angular flexibility and an intermediate length that provides critical extra reach in tight mechanical assemblies where standard or deep sockets cannot fit.
Key Features
12-Point Universal Design: Provides a flexible joint and 12-point opening, making it ideal for accessing fasteners at difficult angles in confined spaces.
TorquePlus™ High-Performance Design: Features a radius-corner internal configuration that shifts stress away from fastener corners and onto the flats, allowing for increased torque while preventing rounding.
Aerospace Specification Grade: Meets and exceeds stringent AS4984A specifications, featuring a thicker nickel-chrome coating for maximum corrosion resistance and durability.
Intermediate Length Advantage: Offers a balanced length that provides more reach than a standard socket without the bulk of a deep socket, maintaining superior accessibility.
Full Polish Chrome Finish: Heat-treated alloy steel construction with a mirror finish ensures a professional look, exceptional rust resistance, and easy cleanup.
