Aluminum Binding Screw Posts 
Aluminum screw posts are the traditional and popular choice when it comes to screw posts. And we have a lot of different colors and sizes available, anywhere from 1/8" to 7"! Plus, we have matching screw post extensions, in case you need to go bigger. They are great for binding larger documents. And what makes screw posts unique are their versatility and inexpensiveness. They make excellent binding for sample and swatch books, architectural and engineering portfolios, photo books, leather goods, and other materials. Take a look at the options we have available.
