What Are Architectural Binding Posts (Chicago Screws)?
Architectural binding posts, also known as Chicago screws or sex bolts, are versatile two-piece fasteners consisting of a threaded barrel and a matching screw. They are designed to securely clamp materials together while providing a clean, finished appearance on both sides.
These fasteners are widely used in architectural and industrial applications, including panel systems, railings, signage, cabinetry, furniture, display fixtures, elevator gates, HVAC ventilation systems, and general construction.
The knurled barrel design helps prevent rotation during installation, allowing for convenient one-sided assembly and improved fastening stability.
They are commonly used as architectural panel fasteners and through-panel fastening solutions.
How to Install Architectural Binding Posts
Installation is simple and can be completed from one side:
- Insert the barrel through the pre-drilled hole in the material.
- Align the components to ensure proper fit.
- Insert the matching screw from the opposite side.
- Tighten the screw using a suitable driver (slotted or Phillips) until secure.
The knurled barrel helps prevent rotation during tightening, ensuring a stable and secure connection.
Applications
Architectural binding posts are widely used in:
- Architectural panels and wall systems
- Railings and glass installations
- Signage and display fixtures
- Cabinetry and furniture assembly
- Elevator gates and door hardware
- HVAC ventilation systems
- General construction and industrial applications
- Ideal for both structural and decorative fastening applications
- Custom sizes, materials, and finishes available to meet your project requirements.
