Using this DeWalt socket set is a breeze. To start, select the right socket size for your fastener. Then, fit the socket onto your 3/8' drive tool. You can use it to both tighten and loosen fasteners in either direction. When using, make sure the socket is properly seated on the fastener to avoid slipping. This non - slip design helps reduce wear on the fasteners. As for maintenance, after each use, wipe the sockets clean with a dry cloth. The chrome finish resists corrosion, but it's still a good idea to store the set in a dry place. Also, don't use the sockets on fasteners that are too large or too small for them, as this could damage both the sockets and the fasteners.
