Be the first to write a review

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

Details

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 binding bolts 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.

Aluminum Screw Post + Chicago Screws Expert Review

 

I RECOMMEND THIS FOR: 
Aluminum screw posts are my personal favorite option when it comes to screw post binding. They are easy to bind and unbind, and are available in a huge variety of sizes as well as extending options to allow for any capacity. They are ideal for anyone who may need to modify the items bound (photo books, presentations, blueprints, etc.), as well as those who need a clean bound look (very professional), and have a high capacity of pages or materials to bind (such as large machinery manuals, scripts, etc.).
 

WHAT I LIKE:
Aluminum Chicago screws are great because they are made of metal, which is easy to screw together and unscrew, as needed. There are no threading difficulties when trying to get both ends straight in order to connect properly; they are smooth and easy to work with. In addition, they come in the largest variety of sizes of all our screw posts, from tiny 1/8” posts up to 5” long. And the capacity can even be expanded further by adding the post extensions. For this reason, these metal screw posts offer the thickest potential binding capacity of any other binding method (possibly, with the exception of screw lock binding rings). They are also stocked in a couple different colors (black, gold, antique brass, silver), so you are not stuck with just plain silver male and female posts.

In addition, I like screw post bindings because they are fairly inexpensive, costing as little as about 7¢ each, depending on the size and color you choose. We also offer bulk pricing for larger quantities that can get the cost down lower; just call (866)537-2244 for a quantity discount quote.

Metal screw posts are also very versatile, and can be used for any application that has a standard size hole punch, no matter how many holes you have in the document. Bind just the corner with 1 Chicago screw, or put 3 in each document using the hole pattern of a standard 3-hole punch (many options available here). Bind the top, or bind the side...there are no restrictions.
 

THINGS TO CONSIDER:
As you add more extensions, the stability of the binding post will become less strong. For that reason, if you plan to bind what will become a very large book, such as 7” thick, you should buy the longest post available (5”) and then extensions. Sometimes customers will buy 2” posts, expecting to extend them larger over time, but it is not recommended to begin with something so much shorter than your final length.

You should also keep in mind that the smaller posts (female side) have a hole in the head. The purpose of this is to allow for more threading, and more strength-of-bind, however, some customers do not like the look of this. This is the case for screw posts up to (and including) 3/8”. Anything larger will have a slot for a flat head screwdriver. The screw end (male side) always has a flat slot (note: even though they are slotted for a screw driver, they are easily bound tightly with just your hands).
 

THE BOTTOM LINE: 
Screw post binding works well for anyone (individual or business) who needs to bind an editable document quickly, without any machinery, and easily. You can use 1, 2, 3, or more screw posts per book, depending on your preference. They come in a couple professional colors, and a huge range of sizes to allow for very thick books up to 5”, or even larger when you add extensions. Still not quite sure aluminum Chicago screws are right for you? Call us at (866)537-2244 or fill out this form to request a sample to test before you buy.
