Socket 3/8" Drive 3/8 12 Pt Universal - Stanley Proto Industrial Tools

Part #: 5273

The Stanley Proto 5273 3/8" Drive 3/8" 12-Point Universal Socket is engineered for professional technicians and mechanics seeking reliable performance in demanding environments. This versatile socket provides enhanced accessibility and efficient fastener engagement, making it an indispensable tool for a wide range of automotive and industrial applications.

Key Features

  • 12-Point Configuration: Designed for quick and easy alignment, the 12-point geometry allows for efficient engagement with fasteners in tight or obstructed spaces, reducing fumbling and improving productivity. It is compatible with both square and hexagonal fasteners, as well as 12-point bolts.
  • TorquePlus™ Design: Featuring Proto's proprietary TorquePlus™ design, this socket engages fasteners on their flats rather than corners. This radius-corner design minimizes slippage, reduces the risk of fastener rounding, and extends the life of both the fastener and the tool. It also aids in turning worn, rounded, or rusted fasteners more easily.
  • Professional-Grade Construction: Manufactured from durable alloy steel, this Stanley Proto socket is built to withstand the rigors of daily professional use, offering long-lasting durability and consistent performance.
  • Universal Joint Functionality: The universal design provides flexibility, allowing the socket to pivot and reach fasteners at various angles, which is crucial when working in confined areas where straight-on access is not possible.

Applications

This 3/8-inch drive, 3/8-inch 12-point universal socket is ideal for various professional tasks where maneuverability and reliable fastener engagement are critical. Common use cases include automotive repairs, particularly for hard-to-reach bolts within engine compartments or chassis. It is also well-suited for heavy machinery maintenance, industrial assembly, and other fastening jobs in confined workspaces across construction and industrial settings. While highly versatile, 12-point universal sockets are generally best suited for hand tool applications rather than extremely high-torque impact use.
