S-92365A489 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in demanding industrial environments
• Efficient thread forming capability creates strong, permanent threads in steel and sheet metal without pre-drilling
• Integrated No. 3 drill tip with 1/4" length penetrates up to 0.175" thickness, eliminating separate drilling operations
• Precision 82° countersink angle ensures flush mounting with standard flat head profiles for clean, professional finishes
• Phillips No. 2 drive system provides secure tool engagement and reduces cam-out during high-torque installation
• Full threading along the 3/4" length delivers maximum grip and load distribution across the entire fastener
• BSD thread forming design creates vibration-resistant connections that maintain integrity under stress

Professional Applications & Engineering Value

These black-oxide steel tapping screws are engineered specifically for steel and sheet metal applications where traditional fastening methods fall short. The thread forming technology eliminates the need for tapped holes, reducing installation time by up to 50% while creating stronger, more reliable connections. The integrated No. 3 drill tip with 1/4" length penetrates materials up to 0.175" thick, making them ideal for HVAC systems, electrical enclosures, and automotive assemblies. The fully threaded design ensures maximum engagement in thin materials, while the 82° countersink angle provides a clean, flush finish that meets professional appearance standards. These BSD screws are particularly valuable in high-volume production environments where efficiency and reliability are critical.

Specification Summary & Compliance

Manufactured to precise inch system standards with No. 10-16 thread diameter and 16 threads per inch configuration. Features right-hand threading with standard Class 2A thread tolerances for consistent performance. The flat head profile with 0.362" head diameter and 0.116" head height ensures proper seating in standard countersunk applications. Complies with industry-standard thread forming screw specifications and meets material composition requirements for industrial fastening applications. The black-oxide surface treatment provides enhanced corrosion protection while maintaining dimensional stability across the 3/4" screw length.
