How to use an Adjustable Wrench

Adjust the Wrench Head: Adjust the opening size of the adjustable wrench by turning the knob. Make sure it is adjusted to the size that matches the bolt or nut.

Place the Wrench: Place the opening part of the wrench into the hexagonal surface of the nut or bolt, making sure the contact surface with the nut is flat.

Turn it hard: Turn it clockwise for tightening and counterclockwise for loosening. Keep the wrench stable when using it to ensure that it does not slip.

Safety Tips for Adjustable Wrenches

Avoid over-force: Although the adjustable wrench has an adjustable function, the force it uses still needs to be controlled. Excessive force may cause damage to the nut or wrench.

Avoid over-adjustment: Every time you adjust, avoid over-turning the adjustment screw, causing it to be too loose or too tight.

Check the size of the wrench head: Make sure the wrench opening matches the size of the bolt or nut exactly. If the opening is too large, it may cause slippage or damage.

Choose the right size: If more torque is required, choose a longer adjustable wrench and avoid using a tool that is too small.

Keep the wrench clean: Make sure the wrench is clean and dry before and after use. Dirt and corrosion may cause the wrench to stick or slip.
