Aluminum screw posts are the most popular kind of binding post. Also called Chicago screws, they are made of a sturdy and durable aluminum that is strong, but affordable. They are packaged with 100 sets per pack, and bulk discounts are often available for larger orders. Call (866)537-2244 to see if your order qualifies.
Choose from several colors -- including silver, black, gold, and antique brass options -- as well as quite a range of sizes from 1/8 of an inch to 5 inches. The post is 3/16 of an inch thick, and will fit into standard punched holes, such as those from a 3-hole puncher. The heads are 7/16 of an inch, and feature a slot on one side so you can use an optional flathead screwdriver. Smaller sizes also have a hole on the opposite end to allow enough room for a tight bind. Plus, they are incredibly easy to use. And because they are loose bindings, you can use as few or as many as you need to bind your pages.
Chicago screws are one of the easiest, cheapest, and fastest ways to bind documents, making them a great book binding solution for users of all kinds, including both individuals or businesses…basically anyone who needs to bind together pages that can be edited, without a machine.
