S-92685A430 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Maximum torque transmission through external hex drive design, preventing tool slippage during installation
• Enhanced vibration resistance with serrated locking flange that maintains secure fastening under dynamic loads
• Self-drilling capability with No. 3 drill tip that penetrates up to 0.187" thick steel and sheet metal without pre-drilling
• Reliable thread forming technology creates strong, permanent threads in parent material for superior pull-out resistance
• Full 1" threading provides maximum engagement length for stronger connections in various material thicknesses
• Precision 14 TPI threading ensures consistent, secure fastening with Class 2A thread tolerances

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws are engineered to solve critical fastening challenges in steel and sheet metal applications. The thread forming technology eliminates the need for tapped holes while creating stronger, more reliable threads that resist vibration loosening. The integrated drill tip with 9/32" length and 0.187" maximum drilling capacity streamlines installation in fabrication shops and assembly lines, reducing labor time and equipment requirements. The external hex drive combined with serrated flange locking ensures maximum torque application and prevents rotation under dynamic loads, making these BSD tapping screws ideal for HVAC systems, electrical enclosures, metal framing, and industrial equipment where vibration resistance and structural integrity are paramount.

Specification Summary & Compliance

These thread forming screws feature precision Class 2A thread tolerances with 14 TPI right-hand threading and comply with BSD tapping screw standards. The fully threaded 1" length with 0.216" thread diameter ensures consistent performance across applications. Manufacturing follows industry standards for zinc-plated steel fasteners, with the external hex drive (0.313" across flats) and 0.52" flange diameter providing reliable installation characteristics. The product meets relevant industrial specifications for steel and sheet metal fastening applications and complies with RoHS and REACH environmental standards.
