S-90064A746 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced installation efficiency through integrated drilling tip that eliminates pre-drilling requirements in materials up to 0.21" thick
• Exceptional holding power with flanged design that distributes clamping force evenly and prevents pull-through
• Reliable thread formation using BSD thread forming technology that creates strong, vibration-resistant connections in steel and sheet metal
• Easy installation and removal with external hex drive design that provides secure tool engagement and high torque capability
• Full-length threading ensures maximum grip along the entire screw length for superior fastening strength
• Precision dimensional consistency with No. 12 size and 14 TPI thread pitch for reliable performance in standardized applications

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws deliver exceptional engineering value by solving critical fastening challenges in steel and sheet metal applications. The innovative combination of thread forming technology and integrated drilling tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs in industrial assembly lines. The BSD thread forming design creates stronger, more durable connections than conventional threaded fasteners by displacing material rather than removing it, resulting in superior resistance to vibration loosening. The zinc-plated steel construction provides reliable corrosion protection in demanding environments, while the flanged head design ensures even load distribution and prevents damage to sensitive materials. These industrial fasteners are engineered specifically for metalworking, construction, and manufacturing applications where reliability and efficiency are paramount.

Specification Summary & Compliance

These tapping screws feature precision No. 12 size with 0.216" thread diameter and 14 TPI thread pitch, manufactured to standard dimensional tolerances for consistent performance. The thread forming design follows BSD specifications with right-hand threads and fully threaded configuration. The external hex drive and hex head design ensure compatibility with standard industrial tools. Manufactured from high-quality zinc-plated steel, these screws meet industry standards for mechanical properties and surface treatment requirements, suitable for various industrial and construction applications requiring reliable metal-to-metal fastening solutions.
