Using the GearWrench 81902 wrench set is a breeze. First, identify the size of the fastener you need to work on, and then pick the matching wrench from the set. Place the open end or box end of the wrench firmly on the fastener. For better leverage, use the long pattern beam to turn the fastener. Remember, since the box end is offset at 15°, it can give you better access in tight spaces. When using the wrenches, avoid applying excessive force that could damage the fastener or the tool itself. After each use, wipe the wrenches clean with a dry cloth to keep the bright chrome finish in good condition. Store the wrenches in the included V rack to keep them organized and prevent them from getting lost. This set is built to last, but following these simple steps will ensure you get the most out of your GearWrench wrenches.
