Key Product Features

• 15° Offset Head: Both open ends are precision-milled and angled at a 15-degree offset. This design maximizes leverage and provides necessary clearance when working in tight or hard-to-reach spaces.

• High Torque Resistance: Forged from high-grade Chrome Vanadium steel, the spanner is built to withstand extreme mechanical stress and torque without bending, breaking, or deforming.

• Precision Jaws: Jaws are precisely ground to exact nominal dimensions to guarantee a secure, snug fit over fasteners. This significantly minimizes fastener slippage, rounding, and stripping.

• Corrosion Resistance: The smooth chrome plating prevents rust and oxidisation, while allowing workshop grease and oil to be wiped clean instantl
