- Radius corner design engages the flats of the fastener, not the corners, providing up-to 15 to 20% more torque while reducing fastener rounding, enhancing the turning of worn fasteners
- EYE-D™ markings optimize size visibility, also providing SAE/metric differentiation
- Unique socket retention method, cold form ball recess, provides consistent secure retention of the socket to the drive tool eliminating the possibility of either a loose fit or tight fit
- Socket wall dimensions are optimized to provide strength while retaining access to restricted fasteners
- Manufactured from high alloy steel using the most up-to-date manufacturing process and heat treat for greater strength and durability

Made of high quality steel (chrome-molybdenum); thorough and exact heat treatment insures the correct balance of strength and durability
Engineered specifically for use with impact tools, using the most up to date industrial specifications
Made to transfer the pressure from the thinnest part of the socket wall toward the thicker section, resulting in increased strength
Allows up to 20% more torque to be applied than on standard hex impact sockets
Lifetime warranty
This fractional impact socket features our high torque drive. This feature limits the amount of wear on the corners of the fastener and the socket. It also improves the strength of the socket, transfers increased torque to the fastener and allows easier access to tight areas. Each socket is thoroughly made with the correct balance of strength and durability and is tested to the highest specifications to deliver outstanding performance at the most competitive cost.
