1-1/2" Drive x 3-1/8" Standard

• 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
