Introduction
In the world of fine leathercraft, details matter — and hardware is no exception. Among the most versatile fasteners used by leather artisans today are Chicago screws. Compact, reusable, and elegantly functional, these two-part metal posts offer both strength and subtlety in design. Whether you're assembling a belt, a modular strap system, or a refined leather bag, understanding how and when to use Chicago screws can elevate both your craftsmanship and the longevity of your work.

What Are Chicago Screws?
Also known as binding posts or screw posts, Chicago screws are two-part fasteners consisting of a threaded barrel and a matching screw. Originally used in bookbinding, they’re now common in leather goods thanks to their versatility and clean aesthetic.


Why Use Chicago Screws in Leathercraft?
Unlike permanent fasteners like rivets, Chicago screws can be removed and reused. They’re perfect for adjustable belts, modular bag components, leather straps, and other designs that may require maintenance or flexibility. Their strong hold and elegant finish make them a favorite among makers who value both form and function.
How Do Chicago Screws Work?
Installation is simple:
- Punch a hole in each leather layer.
- Insert the post through the layers.
- Fasten the screw into the post from the opposite side.
You can apply a thread locker like Loctite to prevent loosening over time. Slotless versions are also available for a minimal look.
Common Sizes and Materials
Chicago screws come in different post lengths and head diameters to suit varying thicknesses of leather. Common materials include:
- Solid Brass – Patinas beautifully, corrosion-resistant.
- Nickel-Plated Brass – Clean, shiny silver tone.
- Stainless Steel – Strong and rust-proof.
To ensure a tight fit, choose a post length that closely matches your leather thickness.
