There are also 3/8 - inch drive 6 - point impact sockets with the same metric and SAE sizes, a 3 - inch 3/8 - inch drive impact extension, and a 3/8 - inch drive impact universal joint. The sockets are made of heat - treated CR - 440 steel, feature high - visibility laser - etched markings, are compatible with O - rings and retaining pins, and have a black oxide coating. This set is measured in both metric and standard/metric systems, weighs 9.7 lbs, and offers a great solution for various impact - related tasks.

Using this DeWalt socket set is easy. First, pick the right socket size for your fastener. Just slide the socket onto your 3/8 - inch drive tool. If you need to reach a hard - to - get area, attach the impact extension or the universal joint. When you're using it, make sure your tool is set at the right torque to avoid damaging the sockets or fasteners. As for maintenance, after each use, wipe the sockets clean with a dry cloth. If they're really dirty, you can use a mild soap and water solution, then dry them thoroughly. Store the set in a dry place to prevent rust. Also, check the O - rings and retaining pins regularly to make sure they're in good condition. That way, your socket set will last a long time and keep working great.
