Be the first to review this product

Aluminum screw posts are popular solution for quickly binding stacks of paper that need to be frequently edited, or binding 3-hole punched pages that do not belong in a ring binder. With one male (screw) end and one female (post) end, the two pieces of a binding screw are easily attached and detached as-needed by simply screwing them together or apart. This easy binding method also makes them a great choice for photo albums, swatch books, blueprints, engineering drawings, and much more. Also commonly called Chicago screws or Chicago screw posts, these book binding posts are available in several colors including traditional silver, black, gold, and antique brass. In addition to several colors, you can buy aluminum screw posts online in a huge selection of sizes from as small as 1/8" all the way up to 5". We even offer screw post extension pieces that can be added to expand the capacity even larger!

Product Description

Aluminum screw posts have been a popular book binding solution for a long time, as they are extremely easy to put together and take apart, and require no machines or special training to use. Binding screws are simply that: screws. They are a two-piece binding solution that has one post side (female side) and one screw side (male side) that are screwed together to bind. To un-bind, they are simply unscrewed. Because they can be easily bound and unbound quickly, they are a great choice for photo book binding, blueprint and engineering drawing binding, and presentations that might be edited or changed in the future. 

Also called Chicago screws or Chicago screw posts, they come in a large selection of sizes from as small as 1/8" up to as large as 5". We also offer screw post extensions  so you can bind even thicker books. We offer steel screw posts and plastic binding screws as an alternative, however, these aluminum Chicago screws are the most popular option that we offer because of the larger range of sizes available, the perfect blend of affordability and strength, and their ability to easily be edited.

All of our aluminum screw binding posts feature one slotted side. For small screw posts up to 3/8", the other side features a hole that allows the screw to bind tightly with the post, creating a more secure bind. For large screw posts, however, the other side is smooth, as the post is long enough to create a strong bind with the screw without needing that additional length provided by the hole.

Start quickly and easily binding thin and thick books that need to be edited frequently when you buy aluminum screw posts online. Choose a color that best suites you needs; they are available in traditional silver screw posts, black screw posts, gold screw posts, or antique brass screw posts. All colors and sizes are packaged with 100 sets per pack, which means you receive 100 male screws and 100 female posts.
