S-92365A427 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Efficient self-drilling capability with a specialized No. 2 drill tip that penetrates up to 0.09" thickness, eliminating pre-drilling and speeding up assembly.
• Reliable thread forming design creates strong, permanent threads in steel and sheet metal, ensuring excellent vibration resistance and holding power.
• Optimized drive engagement with a Phillips No. 2 drive and flat head, providing secure fastening and a flush finish with an 82° countersink angle.
• Full 2-inch threading offers maximum grip length and uniform stress distribution for secure fastening in various material thicknesses.
• Precision-engineered dimensions including a 0.138" thread diameter and 20 threads per inch, ensuring consistent performance and interchangeability.

Professional Applications & Engineering Value

These No. 6 zinc-plated steel tapping screws are engineered to solve critical assembly challenges in steel and sheet metal fabrication. The thread forming design cold-forms mating threads, reducing the risk of stripping and providing superior pull-out strength compared to cutting screws. The integrated drilling tip and fully threaded shank allow for rapid installation without pilot holes, significantly reducing labor time and tooling costs. The zinc plating offers a protective barrier against oxidation, making these BSD tapping screws ideal for HVAC, automotive, and electrical enclosure applications where durability and speed are paramount. The Phillips flat head design ensures a secure, flush fit, maintaining structural integrity and a clean aesthetic finish.

Specification Summary & Compliance
