Proto 3/8Drive 12PT HUJ Socket 11/16 J5278AS-SBD

Proto's professional-grade 3/8-inch Drive 11/32-inch 12-Point Intermediate Universal Socket, precision-engineered for high-performance industrial and aerospace maintenance. This specialized tool features a pin-system universal joint for smooth angular flexibility and an intermediate length that provides critical extra reach in obstructed areas where standard or deep sockets cannot easily fit.
Key Features
12-Point Universal Design: Features a robust pin-system joint that allows for rotation at angles up to 65°, making it essential for accessing fasteners in tightly packed mechanical assemblies.
TorquePlus™ High-Performance Design: The internal configuration grips the flat surfaces of the fastener rather than the corners, shifting stress away from the points to allow for higher torque and preventing rounding.
Intermediate Length Advantage: Offers a balanced profile that provides more reach than a standard universal socket without the bulk of a deep-length version, maintaining superior accessibility.
Aerospace Specification Grade: Meets and exceeds stringent AS4984A and ASME B107.110-2012 standards, ensuring durability and high corrosion resistance for critical applications.
Full Polish Chrome Finish: Heat-treated alloy steel construction with a mirror finish ensures exceptional rust resistance and makes cleanup of oil and grease effortless.
