We all know how ’shaky’ or unstable a spring can be, due to locked tension within it. And the hassle really surfaces when you’re trying to install bare springs into fixtures — especially when the compressed forces get released accidentally and the spring flies out — most likely in the most unpredictable direction.
This problem can be easily overcome with the use of spring plungers.
A spring plunger is just a hollow, threaded body that holds the spring inside it. A plunger is attached to one of the cylinder, which conveys the spring force. Now, since the spring is ‘captured’ inside the body, it cannot ‘escape’, and all you need to do it lock it into place using the threads. The end of the body is designed to make used of an allen key or a screwdriver.
