S-90064A747 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in industrial environments.
• Enhanced torque transmission and secure installation via the external hex drive and flanged head, which distributes load evenly and prevents pull-through.
• Efficient thread-forming BSD technology creates strong, permanent threads in steel and sheet metal without pre-tapping, reducing assembly time and tooling costs.
• Integrated No. 3 drilling tip allows for self-drilling up to 0.21" maximum thickness, eliminating the need for separate pilot holes and speeding up production.
• Full threading along the 7/8" length provides maximum grip and holding power across the entire fastener engagement area.
• Precise No. 12-14 thread sizing with 14 threads per inch ensures reliable, vibration-resistant connections in demanding applications.
• Right-hand thread direction offers standard, intuitive installation compatible with common power tools and manual drivers.

Professional Applications & Engineering Value

Engineered for steel and sheet metal fabrication, these zinc-plated steel flanged tapping screws deliver exceptional value by combining drilling and fastening into one operation. The thread-forming BSD design cold-forms mating threads, eliminating chip formation and providing superior resistance to loosening under vibration—a common issue in automotive, HVAC, and machinery assembly. The No. 3 drill tip and fully threaded shank ensure rapid penetration and consistent clamping force, while the external hex drive and flange enhance torque control and surface distribution. This design minimizes installation steps, reduces labor costs, and increases structural integrity in high-stress environments.

Specification Summary & Compliance

This No. 12-14 flanged tapping screw features a thread diameter of 0.216" with 14 threads per inch, right-hand threading, and a length of 7/8". Manufactured to BSD (British Standard Drilling) specifications for thread-forming applications, it ensures precise fit and performance. The zinc-plated finish provides basic corrosion protection, and the product complies with industry standards for dimensional accuracy. Materials and processes adhere to RoHS and REACH environmental directives, supporting safe and sustainable industrial use.
