• The sockets are made from
  high quality alloy (chrome-molybdenum)
• They are heat treated to
  provide the correct balance of strength and durability
• The impact socket’s “high
  torque” drive provides increased strength through the transfer of
  pressure from the thinnest part of the socket wall toward the thicker
  section
• The sockets feature 20
  percent more torque than on standard hex impact sockets
• There is an increase to
  tight areas through pressure shift to reduce the socket wall thickness
• There is a reduced wear and
  chance of rounding off fasteners by the grip the sockets provide on the
  fastener across a broader contact area
