  • Grey Pneumatic Impact Sockets are designed for professional tool users.
  • They are engineered specifically for use with impact tools, using the most up to date industrial specifications.

Benefits of the Grey Pneumatic Impact Socket “High Torque” Drive
  • Increased Strength-Transfers the pressure from the thinnest part of the socket wall toward the thicker section, resulting in increased strength.
  • Increased Torque-Allows up to 20% more torque to be applied than on standard hex impact sockets.
  • Easier Access to Tight Area-The shift in pressure allows us to reduce the socket wall thickness, increasing access to tight areas.
  • Reduced Wear-The impact sockets grip the fastener across a broader contact area, reducing the chance of rounding off fasteners.
