Silver Aluminum Screw Post Fasteners (often referred to as Chicago Screws, Chicago Screw Posts, or Male & Female Screws) are a great choice for binding photo albums, swatch books, scripts, architectural blueprints, engineering drawings, or any application where loose sheets need to be kept together. Binding with screw posts allows for easy editing without damaging the bound materials. Expanding the screw post's capacity is also made easy by simply attaching our Aluminum Screwpost Extensions. Screw Posts are extremely easy to use, and require no equipment. All you need is a standard hole punch. The silver aluminum finish screw posts are the classic choice for chicago screw binding.
