Using the DeWalt DWADEND38716 double-ended nut driver is easy. First, pick the right end (3/8 or 7/16 inch) for your fastener. Insert it into your impact driver or wrench. Then, align it with the fastener and start the tool. The strong magnet will hold the fastener in place, making your job quicker. When you're done, if the sockets get dirty, you can easily detach them for cleaning. Just take them off, clean them with a brush and some cleaning solution, and let them dry. As for maintenance, store the nut driver in a dry place to prevent rust. Avoid using it for jobs that are beyond its capacity, as this could damage the advanced hardening. With proper use and care, this nut driver will serve you well for a long time.
