The Steelman 78539 6-Spline Small Diameter Socket is an essential tool for professional technicians and mechanics working with specialized fasteners.

  • Small Diameter and Thin Wall Profile: Expertly designed to navigate tight clearances and fit into narrow lug nut wells without damaging expensive wheels.
  • Professional-Grade Construction: Constructed from heat-treated chrome vanadium steel with a corrosion-resistant black oxide finish for exceptional durability and long-term reliability in demanding automotive and industrial environments.
  • Extended Reach Design: Features an extra-long profile to keep wrenches away from wheel surfaces, preventing nicks and scratches during use.

Applications

  • Automotive Wheel Service: Ideal for the removal and installation of aftermarket locking lug nuts that feature a 6-spline, small diameter design, protecting both the fastener and the wheel.
  • Tight Access Fasteners: Designed for situations where standard sockets cannot reach due to limited space, such as in cramped engine bays or on specialized vehicle components.
