S-93380A300 12-24 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Self-tapping efficiency – Cuts precise threads in aluminum, brass, and sheet metal without pre-tapping, reducing installation time and labor costs.
• Superior corrosion resistance – Chrome-plated steel construction ensures long-lasting performance in demanding industrial environments.
• Optimized head design – Undercut flat head with 82° countersink angle provides a flush, secure fit that minimizes surface protrusion.
• Reliable drive engagement – No. 3 Phillips drive offers excellent torque transfer and reduces cam-out during high-torque applications.
• Coarse UNC threading – 12-24 coarse thread ensures quick assembly and strong holding power in softer materials.
• Full-threaded shank – Maximizes grip length and distributes load evenly for enhanced joint integrity.
• Regulatory compliance – Meets RoHS 3 (2015/863/EU) standards, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

These thread cutting tapping screws are engineered to solve common fastening challenges in aluminum, brass, and sheet metal assemblies. The F-type thread cutting design eliminates the need for separate tapping operations, significantly reducing assembly time and tooling costs. Made from chrome-plated steel, they offer excellent resistance to corrosion and wear, ensuring reliable performance in HVAC, electronics enclosures, and automotive components. The undercut flat head design allows for a clean, flush finish that prevents snagging and improves aesthetic appeal. With a No. 3 Phillips drive and coarse 12-24 UNC threads, these screws provide quick installation and strong vibration resistance, making them ideal for high-volume production environments where efficiency and durability are critical.
