Chicago screws are sold in sets of 100 (100 screws & 100 posts). Screw post extensions are 100 per box.



Screw posts, also known as Chicago screws or book binding posts, are extremely versatile binders that allow loose documents of practically any shape or size to be securely bound together. These low-cost, reusable Chicago screws enable you to easily change out bound documents, making them a great choice for price books, menus, swatch books, architectural and engineering drawings, and much more. Our high quality, antique brass-colored aluminum screw posts provide an easy-to-use alternative to other binding methods at an exceptionally low price point. Their two-piece construction allows for no-fuss updates, which is why they're an ideal choice for applications that require frequent updates. They are also easy to expand, with a number of screw post extensions readily available.

Great. Co. Good prices fast service

by -

I used it for my neck knives this they don't rust

About what I was expecting

by -

Perfect for my intended use - price and shipping was incredibly appealing. Customer service was exceptional. Only reason this product is getting 4 stars is because the aluminum is very soft and the slots for the flat head screwdriver are fairly wide resulting in a few stripped bits. Not a problem, for the price I am not too concerned. I recommend this seller and product (for light use).

Worked better than Pop RIVETS in my case

by -

I replaced pop rivets with your binder screws. Worked great!! I needed a flat surface on both ends. Rivet is flat on one side & has a knot on the other. I used them to fasten DZUS connector brackets to the fiberglass body on my race car. Worked better than I hoped for. Showed couple people that work with fiberglass!They thought it was good idea!

Head of screw so soft comes off

by -

I purchased these screws to attach my conchos that take a Chicago Screw however they do not fit the conchos and when you try to tighten them the metal is so soft that it comes right off...unfortunately I did not keep my receipt or the return box so I am stuck with them...very unhappy and feel the product was misrepresented as they are not Chicago Screws at all.

Just what I was looking for

by -

The head of this screw is a bit bigger than I hoped, but useful for a secondary project.

Lowest price I found on the internet

by -

Worked fine. Used it to hold sample materials together.

I would buy this product again

by -

Used to assemble a proportions gauge. I use it when drawing woodworking projects.

1/8 inch binder screws

by -

Need to be very careful assembling these, or disassembling. Crossthread and jam very easily. Order 10% extra for waste.

Worked just fine.

Worked well.
