I ordered these and used them temporarily. They were very good quality. Heavy, well built, and good looking. But, keep in mind set-screw type terminals are prone to a few problems. For this reason I swapped them out. The wire can vibrate and wiggle out of the connector after time and vibrations. Even more importantly, they are not great for the connection they provide. The only point of connection is where the set screw screws down into the middle (not the entire width) of the wire. The benefit of this type is obviously that they can be re-used. Otherwise, I would strongly recommend crimping (with a crimping tool) and/or soldering your terminals instead. It provides a much stronger and better connection than set screws can. You can buy a simple hammer type crimper for $20-25. I prefer a hydraulic crimper, which you can even find from Harbor Freight, that is only $50 and puts 8 tons of force on the crimp.
