S-96231A400 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• Efficient thread forming design that creates strong, reliable threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Secure fastening with Phillips drive and flat head, providing a flush finish and easy installation with standard tools for consistent results.
• Optimized for sheet metal applications with a pointed tip and 82° countersink angle, enabling precise alignment and reduced material stress.
• Full threading for maximum grip along the entire length, enhancing holding power and vibration resistance in dynamic loads.
• Compliance with RoHS 3 and REACH regulations, ensuring safe, environmentally responsible use in global supply chains.
• Durable brass-colored finish that adds aesthetic appeal while maintaining functional integrity in visible assemblies.

Professional Applications & Engineering Value

These No. 4-24 thread forming tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and loosening under vibration. Made from zinc-plated steel, they offer excellent resistance to rust and wear, crucial for outdoor or high-moisture environments. The flat head with an 82° countersink ensures a smooth, flush surface, preventing snagging and improving safety in assemblies like HVAC systems, electronic enclosures, and automotive panels. By eliminating the need for pre-drilled threads, these A/AB type screws reduce labor costs and streamline production, while the fully threaded design distributes load evenly, minimizing the risk of strip-out in thin-gauge metals. Ideal for industrial fastening, they provide reliable performance where precision and durability are paramount.

Specification Summary & Compliance

This tapping screw adheres to standard inch measurements with a thread diameter of 0.112" and 24 TPI, ensuring precise fit in sheet metal applications. It features a Class 2A thread fit for consistent engagement and a Phillips No. 1 drive for compatibility with common tools. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it meets stringent environmental and safety standards for industrial use.
