S-92365A487 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with a specialized drilling tip that penetrates up to 0.1" thickness in steel and sheet metal, saving significant labor time and costs.
• Superior corrosion resistance provided by the Black-Oxide steel coating, ensuring long-term durability and reliability in harsh industrial environments.
• Enhanced driving efficiency with the No. 2 Phillips flat head, offering a secure fit and reducing the risk of cam-out during high-torque installation.
• Maximum holding power due to the fully threaded design and thread forming (BSD) action, which creates strong, vibration-resistant fastenings in metal substrates.
• Clean, flush finish achieved with the 82° countersink angle and standard flat head profile, ideal for applications where a smooth surface is critical.
• Consistent, reliable performance ensured by the precise No. 8 screw size with 0.164" thread diameter and 18 threads per inch, providing predictable and repeatable fastening results.

Professional Applications & Engineering Value

These Black-Oxide steel tapping screws are engineered to address common challenges in metal fabrication and assembly, such as the need for speed and reliability without pre-drilled holes. The thread forming BSD type design creates strong threads in ductile materials like steel and sheet metal, reducing the risk of stripping and providing excellent resistance to loosening under vibration. The combination of the self-drilling tip and fully threaded shank ensures rapid installation and superior clamp load, making them ideal for high-volume production lines, HVAC systems, and automotive components where efficiency and joint integrity are paramount. The Phillips flat head with an 82° countersink allows for a neat, recessed finish, meeting both functional and aesthetic requirements in professional settings.

Specification Summary & Compliance

This No. 8 x 3/4" tapping screw features a thread diameter of 0.164" with approximately 18 threads per inch, adhering to standard inch measurement tolerances for consistent performance. Manufactured as a thread forming BSD type with a right-hand thread direction and fully threaded design, it is compliant with industry-accepted specifications for self-drilling fasteners. The product is designed for use in steel and sheet metal applications, with a maximum drilling thickness of 0.1", and meets relevant material and safety standards for industrial use, including typical RoHS and REACH compliance for the Black-Oxide coating.
