Square Head Set Screws: Tip pressure prevents objects from moving relative to one another in assemblies where one object is housed inside another. The square head enables wrench tightening and also an easier wrench grip for nut tightening. Used in new construction to mimic an older aesthetic or in railway applications. Set screws come in a variety of different points, cup point being the most common.
