Screw Posts

Do you find that you regularly bind thick materials? Photo books, sample books, plans, menus, swatch books, and more can be machineless bound. With the correct resources, you can build affordable, professional-looking covers. Binding101 includes everything you need to protect scripts or swatches for design projects. We offer metal and plastic binding screw posts for any application. Discover what you need now.


Screw post binding is robust, cheap, and easy. Screw-and-post binding requires no machines or training. Aluminum binding screws, sometimes called Chicago screws or Chicago screw posts, are needed for often updated papers or three-hole punched pages that don't belong in a ring binder. We provide black, gold, silver, and antique brass. We offer 1/4- to 2-inch zinc-coated steel binding screw posts. Pages can be readily modified with these binding screws.


Shop our variety of plastic screw posts to streamline your machineless binding procedure. We offer looped, push-lock, and snap-lock binding screw posts. Our Chicago screws are customized if you can't find the right ones. Add post extensions to increase screw post capacity.
