Description Tested to the highest specifications to deliver outstanding performance at the most competitive cost. Reduces Wear - Our impact sockets grip the fastener across a broader contact area, reducing the chance of rounding off fasteners. Designed for professional tool users. Engineered specifically for use with impact tools, using the most up to date industrial specifications Made from high quality alloy steel (chrome-molybdenum). Thorough and exact heat treatment ensures the correct balance of strength and durability. Increased Strength - Transfers the pressure from the thinnest part of the socket wall toward the thicker section, resulting in increased strength. Easier Access to Tight Areas - The shift in pressure allows us to reduce the socket wall thickness, increasing access to tight areas. Increased Torque - Allows up to 20% more torque to be applied than on standard impact sockets. Set Includes: Universal joint sockets: 1" ? 24mm Molded Storage Case.
