The Mobi Car Cross Wheel Spanner (also known as a 4-way wheel spanner) is a universal emergency tool designed for removing and tightening lug nuts on vehicle wheels. Its cross-shaped design allows you to apply significant torque using both hands, making it much more effective than the standard "L-shaped" wrenches provided with most vehicle toolkits.
Key Performance Features
- 4-Way Versatility: Features four different socket sizes, typically covering the most common nut sizes for passenger cars and light commercial vehicles: 17mm, 19mm, 21mm, and 23mm.
- Heavy-Duty Construction: Forged from hardened carbon steel with a chrome or silver finish to provide high torque strength and resistance to rust.
- Maximum Leverage: The cross-arm design allows for a balanced, two-handed grip, which is essential for loosening over-tightened or rusted wheel nuts.
- Reinforced Center: The central joint is typically reinforced to prevent the arms from bending or snapping under heavy pressure.

Usage & Safety Tips
- Correct Size: Ensure you are using the exact socket size for your wheel nuts. Using a size too large (e.g., 21mm on a 19mm nut) will "round off" the nut, making it impossible to remove.
- Safety First: Only use the spanner when the vehicle is on a flat, stable surface with the handbrake engaged. Loosen the nuts slightly before jacking up the car.
- Storage: Its flat profile makes it easy to store in the boot of a car, usually fitting neatly next to the spare wheel.
