1 piece Mini-buttons are give the advantage is the smaller railbuttons with the convenience being all in one piece.
They are made using Delrin for better wear resistance.
They also designed to be used with a flat head screw that is countersunk for a clean appearance and less drag.
Both are designed to be used with the 80/20 20mm rail. (They may not work with some of the off brand extrusions)
They are about 1/3 the size of a standard 1010 railbutton and designed with mid power rockets in mind, but have been used successfully for some high power flights as well.
