Stage fixings
Stage pins are used to hold pin hinges together.
Stage screws are mainly used for fixing adjustable stage braces to the stage to make them more permanent. They are also used for attaching zip lines and metal hardware to the stage.
Set screws are similar to stage screws in look and use, except that they have to fit into a boss plate.
Boss plates are fitted to floors and scenery to take set screws and bolts.
Screw eyes are primarily used on flats as an alternative to a brace cleat. It is screwed into the flat and used as a fixing for the top hook of an adjustable stage brace. However they are also useful for various jobs on stage.
