Professional Applications & Engineering Value
Engineered for demanding industrial applications, these zinc-plated 410 stainless steel tapping screws deliver exceptional performance in stainless steel and sheet metal fastening scenarios. The combination of thread-forming BSD technology and integrated sealing washer addresses critical challenges in metal fabrication, including vibration resistance, environmental sealing, and installation efficiency. The self-drilling tip eliminates secondary operations, reducing assembly time while the external hex drive ensures reliable torque transmission for consistent clamping force. These features make them ideal for HVAC systems, electrical enclosures, and structural metal assemblies where corrosion resistance and long-term reliability are paramount.
Specification Summary & Compliance
This 1/4"-14 x 3" tapping screw features precision right-hand threads with 14 TPI and Class 2A thread tolerances for consistent performance. Manufactured to BSD standards for thread-forming applications, the fastener includes a stainless steel/rubber flat washer with 5/8" OD. The No. 3 drill tip (5/16" length) ensures proper penetration in materials up to 0.21" thickness. Compliant with industry standards for metal fastening applications, these screws meet material specifications for 410 stainless steel with zinc plating for enhanced corrosion protection.
