Stainless Steel Chicago Screws

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

Stainless Steel Chicago Screws (also known as sex bolts or binding barrels) are heavy-duty, corrosion-resistant fasteners designed for permanent or semi-permanent assembly in demanding environments. These two-piece fasteners consist of a male threaded bolt and a female threaded barrel that screw together, creating a clean, flush finish without exposed threads.

Key Features & Specifications

1. Material & Finish

• Material: 304 or 316 Stainless Steel (for maximum corrosion resistance).

  • 304 (18-8 SS): Ideal for general use (indoor/outdoor).

2. Design & Construction

• Two-Piece System:

  • Male Bolt (Post): Externally threaded shaft.

• Flush Mount: Sits nearly flat when tightened for a smooth, professional appearance.

✅ Advantages Over Standard Screws

🔹 Extreme Corrosion Resistance (best for wet/harsh environments).
🔹 High Tensile Strength (stronger than aluminum or brass).

Final Verdict

Stainless Steel Chicago Screws are the ultimate choice for high-strength, weatherproof, and long-lasting fastening in marine, industrial, and outdoor applications. Unlike cheaper alternatives, they won’t rust, break, or loosen easily, making them ideal for critical assemblies.

Stainless steel Chicago screws represent the gold standard for permanent, high-performance fastening across industries. Their combination of mechanical robustness, environmental resistance, and professional finish makes them indispensable for:

• Engineers needing reliable assemblies

• Fabricators requiring durable hardware

• Designers seeking functional aesthetics

For mission-critical applications, specify 316 marine grade with proper passivation. For cost-sensitive projects, 304 grade offers excellent balance. Always match screw length to material thickness for optimal performance.
