Tightener/power supply terminal grip, terminal grip, screw terminal grip

thingiverse

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. Dimensions (in case you need to scale): ID: 11.74mm, spike to spike 9.6mm, # spikes=10, equidistant OD (base): 18mm OD (handle): 22mm Handle height: 15mm (5mm overlap with base) Base height: 14mm (exposed = 9mm) Total height: 24mm
