- Unique modified ear design prevents lock-up at extreme angles, allowing for smooth, continuous operation
- 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
- 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
- Black oxide industrial finish eliminates chance of foreign object damage and contamination in critical environments
