Using your Cougar Pro socket is easy. First, make sure you have the right drive size (3/8') and the correct socket size (17mm) for the job. Just attach it to your socket wrench and start working on your construction, maintenance, or assembly tasks. When using the socket, don't apply excessive force that could damage it. Also, keep it away from extreme heat as it might affect the alloy steel's properties. After use, wipe it clean with a dry cloth to remove any dirt or debris. Store it in a dry place to prevent rusting. Since it has a chrome - plated finish, avoid using abrasive cleaners that could scratch the surface. With proper care, this socket will serve you well for a long time, thanks to its lifetime warranty.
