With this tool you can adjust your dzus springs so that you can use the same size buttons. The hassle of adjusting panel fastener springs is over. No more adjusting with a screwdriver or gripping with a pair of pliers. The panel spring adjuster is quick and easy to use, lightweight and durable. It pulls the spring evenly like a panel button fastener would, so you do not create any kinks or breaks in the spring. With the ability of pushing or pulling the spring with an even amount of pressure and tension applied, the risk of weakening the spring or possible breaking it are now over when you need to adjust it.
