4" Hex Standard Length Fractional 1-1/2" Drive Impact Socket

• 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.
• Grey Pneumatic Impact Sockets are made from high quality alloy steel (chrome-molybdenum).
• Thorough and exact heat treatment insures the correct balance of strength and durability.
• Grey Pneumatic Impact Sockets are tested to the highest specifications to deliver outstanding performance.

• 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.
