The SuperCombo features open ends with special grooves that direct force away from fastener corners to minimize wear.
- Box opening design allows application of higher torque without rounding or deforming hex fastener points
- No contact is made at the fastener corners; the forces are instead placed on the flat surfaces behind the points
- Meets or exceeds aerospace specification AS 954 for 12-point fasteners to provide accurate torque/tension
- Can be used on all common Hex fasteners
- Box and open end openings are identical
