S-92365A412 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• Effortless installation thanks to the thread forming BSD design that creates strong, secure threads without pre-drilling in steel and sheet metal.
• Enhanced driving efficiency with Phillips No. 1 drive, reducing cam-out and speeding up assembly processes.
• Flush, professional finish achieved with the standard flat head and 82° countersink angle, ideal for applications requiring a smooth surface.
• Maximum grip and holding power from the fully threaded design and 24 TPI, providing reliable fastening in materials up to 0.08" thick.
• Quick penetration and reduced setup time with the integrated drilling tip, eliminating the need for separate drilling operations.
• Wide compatibility for use in steel and sheet metal, making these screws versatile for various industrial and construction projects.

Professional Applications & Engineering Value

These No. 4 zinc-plated steel tapping screws are engineered to address common challenges in metalworking and assembly, such as material fatigue and installation delays. The thread forming technology ensures that threads are cold-formed into the base material, reducing the risk of stripping and providing vibration-resistant connections in steel and sheet metal applications. With a fully threaded shank and precise 82° countersink angle, these screws offer consistent clamping force and a seamless finish, ideal for HVAC systems, automotive panels, and electronic enclosures. The drilling tip allows for self-piercing up to 0.08" thickness, streamlining workflows and minimizing tool changes, while the Phillips drive enhances torque transfer for reliable, efficient fastening in high-volume production settings.

Specification Summary & Compliance

These screws adhere to standard inch measurements with a thread diameter of 0.112" and 24 threads per inch, ensuring precise fit and compatibility. Manufactured as BSD tapping screws with thread forming method and right-hand threading, they meet common industrial specifications for fasteners. The flat head profile and drilling tip design comply with typical engineering standards, and the zinc-plated finish provides basic corrosion protection, aligning with general industry requirements for durability and performance in metal fastening applications.
