S-90064A430 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Efficient self-drilling installation with integrated No. 3 drill tip that eliminates pre-drilling in materials up to 0.15" thick
• Enhanced thread-holding power through thread-forming BSD technology that creates stronger, more durable connections in steel and sheet metal
• Secure, vibration-resistant fastening with the integrated flange design that distributes load and eliminates the need for a separate washer
• High-torque installation capability with the external hex drive head that provides superior grip for power tools
• Maximum material engagement with fully threaded shank design ensuring consistent holding strength along the entire length
• Precision fit and compatibility with standard No. 10-16 thread specifications for reliable performance in industrial applications

Professional Applications & Engineering Value

These zinc-plated steel flanged tapping screws are engineered to solve critical fastening challenges in steel and sheet metal applications. The combination of thread forming technology and a self-contained drill tip eliminates multiple steps in assembly, significantly reducing installation time and labor costs. The BSD tapping screw design creates stronger, more permanent threads in parent material without chip removal, preventing loosening under vibration. With external hex drive compatibility and fully threaded construction, these screws deliver maximum clamp load and are ideal for HVAC systems, metal framing, electrical enclosures, and industrial equipment where corrosion resistance and structural integrity are paramount.

Specification Summary & Compliance

This No. 10-16 tapping screw features precise inch measurements including 0.19" thread diameter, 16 TPI thread pitch, and 1/2" length. Manufactured to BSD standard specifications for thread forming screws with right-hand thread direction and Class 2A thread tolerances. The zinc-plated steel construction provides corrosion protection while meeting industry standards for mechanical properties. Suitable for drilling up to 0.15" maximum thickness in steel and sheet metal applications with consistent performance across professional and industrial environments.
