A loose nut on a 1/4" jack is trouble. It's no fun to watch the jack disappear into your guitar or amp as the nut falls off, or to break a solder connection when you tighten the nut and the jack turns with it. Jack The Gripper is an ingenious tool that holds the jack steady so you can tighten or loosen the nut securely without disassembling your instrument or amp.
