S-91515A397 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments.
• Superior fastening stability due to the flanged truss head design, which distributes pressure evenly and reduces the risk of material damage.
• Efficient self-drilling capability with a No. 3 drill tip, allowing for quick installation in steel and sheet metal up to 0.21" thick without pre-drilling.
• Optimized thread engagement from the fully threaded BSD thread-forming design, providing strong, vibration-resistant holds in tough materials.
• User-friendly installation with a No. 2 Phillips drive, enabling secure tool engagement and reducing slippage during high-torque applications.
• Broad compatibility with standard No. 12 size and 14 threads per inch, ensuring easy integration into existing assembly processes.
• Environmental compliance assurance by meeting RoHS 3 standards, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered to address common challenges in metalworking and fabrication, such as time-consuming pre-drilling and fastener failure under stress. The thread-forming BSD design creates precise, durable threads in steel and sheet metal, minimizing the risk of stripping and enhancing load distribution. With a fully threaded shank and flanged truss head, they provide consistent clamping force and resist loosening in high-vibration settings like HVAC systems, automotive assemblies, and industrial machinery. The integrated drilling tip streamlines installation, reducing labor costs and improving project turnaround, while the RoHS 3 compliance ensures they meet rigorous environmental regulations without compromising performance.
