Features:

• SP box ring end spanners feature a deeper flat drive ring making them the perfect spanner for getting to and loosening those tricky, hard to reach, often worn fasteners by increasing the contact area with the nut or bolt head. More contact means greater applied torque
• Flat Drive Technology: Perfectly flat spanner head surfaces allow for maximum contact between the spanner and the bolt or nut, maximising grip and enhancing applied torque
• Reversible
• Chrome Vanadium Steel (Cr-V) for high strength & durability
• Meets & exceeds international ANSI & DIN standard
