Key Features & Benefits at a Glance
- Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.09" thick steel and sheet metal
- Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
- Maximum torque transmission enabled by external hex drive design, preventing tool slippage during installation
- Enhanced load distribution from flanged design that reduces surface pressure and prevents material deformation
- Secure thread formation through BSD thread forming technology that creates strong, vibration-resistant connections
- Full-length threading ensures consistent grip strength along the entire 5/16" fastener length
- Industry-standard compatibility with No. 6-20 thread specifications for reliable interchangeability
Professional Applications & Engineering Value
These zinc-plated steel flanged tapping screws deliver exceptional value in metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations while creating stronger threads than cutting alternatives. The integrated drilling tip specifically engineered for steel and sheet metal applications significantly reduces installation time and labor costs. The external hex drive provides reliable torque transmission for high-volume production environments, while the flanged construction distributes clamping force over a wider area, preventing pull-through in thin materials. This combination of features makes these BSD tapping screws ideal for automotive, HVAC, and electrical enclosure assemblies where vibration resistance and structural integrity are critical.
Specification Summary & Compliance
This No. 6-20 thread forming screw features a 0.138" thread diameter with 20 threads per inch in right-hand orientation. The fastener maintains standard inch system tolerances with fully threaded shank design and precise external hex drive compatibility. Manufactured from zinc-plated steel for corrosion protection, these screws comply with industry standards for BSD tapping screws and are suitable for use in various industrial applications requiring reliable fastening solutions.
