S-92365A448 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates Pre-Drilling: Self-drilling tip with No. 2 drill point penetrates up to 0.11" steel or sheet metal, saving time and labor costs.
• Superior Corrosion Resistance: Zinc-plated steel construction provides a durable protective layer, extending service life in demanding industrial environments.
• High-Strength Thread Engagement: Thread-forming (BSD) design creates strong, permanent threads in metal, ensuring excellent vibration resistance and pull-out strength.
• Efficient Installation: Phillips No. 2 drive offers a common and reliable interface for high-torque driving with standard tools.
• Flush, Professional Finish: Standard flat head with an 82° countersink angle sits flush with the material surface for a clean, snag-free assembly.
• Maximum Holding Power: Fully threaded 1/2" length with 16 threads per inch provides consistent clamping force along the entire shank.
• Wide Material Compatibility: Engineered specifically for reliable fastening in both steel and sheet metal applications.

Professional Applications & Engineering Value

These No. 10 zinc-plated steel tapping screws are engineered to solve critical assembly challenges in metalworking and fabrication. The thread-forming (BSD) design eliminates the need for a separate tapping operation, as the screw cold-forms a mating thread in the material, resulting in zero chip production and a tighter, more reliable fit. The integrated drilling tip and right-hand thread work in tandem to penetrate and secure materials up to 0.11" thick without pre-drilling, drastically reducing assembly time and the risk of worker error. This makes them an indispensable sheet metal screw for HVAC ductwork, electrical enclosures, and automotive panels, where speed, strength, and a flush finish are paramount. The zinc plating ensures long-term performance by resisting rust and corrosion in various industrial settings.

Specification Summary & Compliance

This screw conforms to BSD tapping screw standards with a No. 10 screw size and a 0.19" thread diameter. It features a standard Class 2A thread fit for general applications, a fully threaded shank, and a precise 82° countersink angle for the flat head. Manufactured from steel with a corrosion-resistant zinc plating, these screws are compliant with RoHS and REACH environmental directives.
