Cross recessed Chicago screws

Cross Recessed Chicago Screws (also known as Phillips head sex bolts ou cross drive binding posts) are specialized two-part fasteners designed for applications requiring tool-assisted assembly and a flush, low-profile finish. These industrial-grade fasteners consist of:

1. Male Screw Component

• Features a countersunk flat head with a precision cross (Phillips) recess

• Engineered for secure engagement with standard Phillips screwdrivers

2. Female Barrel Component

• Precision-threaded cylindrical barrel with internal threads

• Typically features knurled or smooth exterior for tool gripping

• Cross recessed Chicago screws

• Designed to fully encapsulate screw threads when assembled

Key Technical Specifications:

• Drive Types: Phillips (standard), Phillips/Square hybrid (for increased torque)

• Materials: 304/316 stainless steel (corrosion resistant), brass (non-sparking), hardened steel (high strength)

• Temperature Range: -40°F to +500°F (material dependent)

Performance Advantages:

• Superior Torque Transmission: Cross recess design prevents cam-out during high-torque installation

• Vibration Resistance: Thread locking variants available (nylon patch or chemical adhesive)

• Corrosion Resistance: Optional marine-grade finishes for harsh environments

Industrial Applications:

1. Transportation Industry: Aircraft interior panels, vehicle trim fastening

2. Heavy Machinery: Vibration-resistant assembly points

3. Architectural Metalwork: Flush-mount structural connections

Installation Specifications:

• Recommended torque settings: 5-25 in-lbs (material/size dependent)

• Cross recessed Chicago screws

• Thread locking compound recommended for permanent installations

This professional-grade fastener solution is particularly valuable in applications requiring repeated disassembly while maintaining structural integrity. The cross recess design offers optimal balance between installation speed and security, making it ideal for production environments.
