Combination spanner
WhatsApp Order
A combination spanner, also known as a combination wrench, is a hand tool used for tightening or loosening nuts and bolts. It typically features an open-end wrench on one side and a box-end wrench on the other. The open-end has U-shaped jaws that grip the fastener from the sides, while the box-end has a closed loop that provides a more secure grip on the fastener’s sides, reducing the risk of slipping. This dual design makes combination spanners versatile and suitable for various applications in automotive, construction, and other mechanical tasks.

SAFETY HANDLING PRECAUTIONS
- Wear Personal Protective Equipment (PPE):
- Always wear appropriate PPE, such as safety glasses or goggles, gloves, and other necessary protective gear, to shield yourself from potential hazards.
- Inspect the Tools:
- Before using the combination spanner, inspect it for any damage, such as cracks, bends, or worn-out jaws. Do not use a damaged tool, as it may fail during use.
- Select the Right Size:
- Ensure that you use the correct size of combination spanner for the nut or bolt you are working on. Using the wrong size can lead to slipping, causing injury or damage to the tool.
- Apply Force Properly:
- Use controlled and steady force when applying torque to nuts and bolts. Avoid excessive force that could lead to the sudden release of the tool, potentially causing injury.
- Position Yourself Correctly:
- Stand in a stable and balanced position while using the combination spanner. Keep your feet shoulder-width apart to maintain balance and prevent tripping.
- Use the Right Technique:
- When using the box-end, ensure that it fully engages with the nut or bolt. For the open-end, position it correctly on the fastener to prevent slipping.
- Avoid Improvised Extensions:
- Do not use improvised extensions on the handle of the combination spanner. Using pipes or other extensions may compromise the tool's integrity and lead to breakage.
- Beware of Sharp Edges:
- Be cautious of any sharp edges on the workpiece or surrounding areas. This includes being aware of potential pinch points to avoid injuries.
- Keep the Work Area Clean:
- Maintain a tidy work area to prevent tripping hazards. Clean up any oil, grease, or debris that may make the workspace slippery.
- Secure the Workpiece:
- Ensure that the workpiece is securely held or clamped in place before applying force with the combination spanner. This prevents unexpected movements that could lead to accidents.
- Know Your Limits:
- If a fastener is extremely tight, use additional tools or techniques rather than applying excessive force with the combination spanner, which may lead to injury or tool damage.
