This is an aid to enable you to get a better purchase/grip on your power supply or bench unit's screw terminals. I find that they are typically too small to allow me to tighten them easily so I made this. For those of us who don't have child sized hands !!
In some of my projects I have a fair amount of current flowing and as a result I need tight terminal connections to keep the resistance low. This is simple tool which fits over my lab equipment terminals (which are sloped) and provides for a 'press fit' so that you can then turn the terminals with ease and get more torque on them to tighten them.
