The Wadfow WSA1120 Combination Spanner 20mm grips heavy fasteners for mechanical and auto repair. Hardened Cr-V steel provides high torque capacity without bending or snapping. At 240mm long, it offers enough leverage for tight bolts while fitting inside standard toolboxes.
Key Features
- Cr-V Steel Construction: High-strength chrome vanadium alloy maintains shape under heavy load. Resists structural deformation during high-torque mechanical repairs.
- Polished Chrome Plated: Fine polished surface prevents oil and grime from sticking. Protects against corrosion from road dust and humidity.
- 240mm Total Length: Extended body increases physical leverage for loosening stuck nuts. Fits 20mm bolts in narrow engine bays.
- Combination Wrench Head: Open end and 12-point box end on one tool. Switches quickly between fast spinning and high-torque tightening.
