GYSI Swivel Impact Extension Sockets

Engineered for high-performance impact applications, Swivel Impact Extension Sockets feature an integrated swivel joint for maximum flexibility. This coupling design allows for seamless rotation, making it easy to tighten fasteners in cramped or awkward angular positions.

Key Features

  • Integrated Swivel Joint: A high-strength coupling allows the socket to rotate freely, providing access to hard-to-reach nuts and bolts.
  • Impact Rated: Built to withstand the rigorous demands of pneumatic and electric impact wrenches.
  • Heavy-Duty Construction: Manufactured from high-grade alloy steel and heat-treated for superior strength to withstand extreme impact forces.
  • Secure Retaining System: Integrated cross-hole retaining design ensures the socket stays securely locked onto your impact tool.
  • Finish: Industrial black phosphate finish for superior corrosion resistance and durability in high-torque environments.
  • Safety Note: Always ensure the socket is securely locked to the drive square using the appropriate retaining pin and ring before operation.
