Professional Applications & Engineering Value

Engineered for steel and sheet metal fabrication, this zinc-plated steel flanged tapping screw addresses critical installation challenges in industrial assembly. The thread-forming BSD design creates precise mating threads without chip formation, eliminating cleanup while providing exceptional pull-out resistance. The integrated No. 3 drilling tip penetrates up to 0.21" thickness, significantly reducing installation time and labor costs by eliminating secondary drilling operations. The external hex drive system ensures reliable torque transmission even in high-vibration environments, while the flanged head design distributes clamping force evenly to prevent material distortion. These fully threaded screws deliver consistent performance in HVAC systems, electrical enclosures, machinery guards, and structural metal assemblies where corrosion resistance and permanent fastening solutions are paramount.

Specification Summary & Compliance

This 1/4"-14 flanged tapping screw features precision right-hand threads with standard inch measurements and BSD thread-forming design compliant with industrial fastening specifications. The zinc-plated steel construction provides corrosion protection meeting industry standards, while the external hex drive and fully threaded shaft ensure consistent performance across applications. Manufactured to exacting dimensional tolerances for reliable installation in steel and sheet metal substrates up to 0.21" thickness, these screws deliver predictable performance in demanding industrial environments.
