Using this US PRO adjustable wrench set is a breeze. First, pick the right wrench size for your job based on the jaw opening requirements.

When you're done, wipe the wrenches clean with a dry cloth to keep them in good condition. Store them in a dry place to prevent rust. Avoid using excessive force that could damage the jaws. With proper use and care, this wrench set will serve you well for a long time.
