1/2 Inch Drive 12-Point Pinless Heavy-Duty Driveline Impact Sock - Astro Pneumatic

Part #: 78250

The Astro Pneumatic 78250 Driveline Impact Socket Set is engineered for professional technicians and mechanics tackling challenging driveline repairs. This comprehensive 1/2-inch drive set features 12-point sockets specifically designed for securely engaging driveline bolt heads on a wide range of vehicles, from domestic and import models to heavy-duty applications. The innovative "torque-saver" extension design ensures maximum power transmission from your impact wrench to the fastener, optimizing efficiency even with smaller impact tools.

Key Features

  • 12-Point Socket Design: Provides a secure and positive engagement with driveline bolt heads, minimizing slippage and rounding, crucial for high-torque applications.
  • "Torque-Saver" Extension: Astro Pneumatic's unique extension design channels more impact energy directly to the fastener, allowing for effective use of smaller class impact wrenches and reducing strain on tools and users.
  • Pinless Universal Joint: Each socket features a pinless universal design that offers a full 360 degrees of freedom, enabling the socket head to angle and rotate freely for superior access in confined or obstructed driveline areas.
  • Heavy-Duty Construction: Forged from durable chrome-molybdenum (CR-MO) steel, these sockets are built to withstand the rigorous demands of professional shop environments, ensuring longevity and reliability under sustained impact use.
  • Comprehensive Size Coverage: The set includes essential 1/2-inch drive 12-point sizes: 12mm, 13mm, 18mm, 1/2 inch, and 3/8 inch, providing versatility for various driveline components.

Applications

This heavy-duty impact socket set is an indispensable tool for servicing driveline components such as universal joints, driveshafts, and differentials. It is suitable for professional automotive repair, fleet maintenance, and industrial applications involving driveline fasteners on domestic, import, and heavy-duty vehicles. Technicians will find it particularly useful in situations where straight access to fasteners is limited, requiring the flexibility of a universal joint.
