Chicago Pneumatic S421MD 1/2 in Drive Deep Impact Socket, 21mm - CP 8940164010

Impact sockets Chrome-molybdenum Steel and Phosphate manganese surface finish for extreme wear resistance, easy to read laser etched marking with output size, and model number.

  • Durable design for extreme wear resistance, maximum torque and preventing fastener rounding
  • Ensure safety - Designed to prevent occurrence of cracks or breaks, and prolonging the life of the socket
