Using your DeWalt DWMT17000 hex socket set is a breeze. First, pick the right socket that matches your fastener size. When you're tightening or loosening a fastener, just fit the socket onto the fastener and use a compatible driver. You can turn it in either direction to get the job done. When using this set, always make sure the socket is firmly seated on the fastener. This will prevent slipping and potential damage to the fastener or the socket. Also, don't use excessive force that could cause the socket to break or strip the fastener. To keep your socket set in top - notch condition, after each use, wipe it down with a clean, dry cloth. If it gets dirty, you can use a mild detergent and water to clean it, then dry it thoroughly. Store it in a dry place to avoid rusting. This way, your DeWalt socket set will serve you well for a long time.
