SP box ring end spanners have a deeper flat drive ring that makes them perfect for reaching and loosening tough, hard-to-reach, often worn fasteners. The increased contact area with the nut or bolt head means more torque can be applied.
Flat Drive Technology: The perfectly flat spanner head surfaces ensure maximum contact with the bolt or nut, providing a strong grip and enhancing torque application.
