The mini binding post with tin contact will allow you to solder a wire on the post side and screw a wire into the other side. This allows you to disconnect the screw side anytime you want.
If this binding post is used with your laser tube, you will be able to change the laser tube much easier just by unscrewing the terminal from the tungsten lead and the new tube can be inserted without re-soldering the wire to the tungsten lead.
