The GearWrench 3/8" Drive Locking Impact Extension (Model 84432) is engineered for professional technicians and mechanics requiring reliable reach and secure socket retention in demanding environments.

  • Secure Locking Mechanism: A robust locking mechanism with a sliding collar securely attaches the socket to the extension, preventing accidental detachment during operation.
  • Corrosion Resistance: The manganese phosphate finish provides superior resistance to corrosion, extending the tool's lifespan in harsh shop conditions.
  • Enhanced Socket Retention: Features a pin hole designed for use with a pin and O-ring, offering an additional layer of secure socket retention, especially crucial with impact tools.
