How to use

Select the adjustable wrench and rotate the adjustment screw until the jaw opening matches the size of the nut or bolt. Place the wrench jaws squarely onto the fastener, ensuring full contact on the flat surfaces to reduce rounding risk. Apply steady manual force to turn the fastener, repositioning your grip as needed. After use, close the jaw to a smaller opening for safer storage and to protect the adjustment mechanism.

Recommendations

Inspect the jaw faces and adjustment screw periodically for wear or debris, and keep the mechanism lightly lubricated to ensure smooth adjustment. Use the wrench within its 15 mm capacity and avoid using cheater bars or excessive force that could damage the tool or fastener. For stubborn or high-torque fasteners, use a correctly sized fixed spanner or socket to prevent slippage and preserve the adjustable wrench's lifespan.
