S-93945A037 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Efficient thread forming design for Type A/AB applications, creating strong, secure threads in sheet metal without pre-tapping.
• Optimal flush installation with an 82° flat head and standard profile, providing a smooth surface finish and reduced snagging.
• Full threading and pointed tip for faster driving and maximum grip length, enhancing assembly speed and holding power.
• Precision compatibility with No. 21 drill bits (0.159" diameter), simplifying hole preparation for up to 0.025" material thickness.
• Right-hand threading for standard installation practices, ensuring ease of use and consistent performance.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, supporting sustainable and safe manufacturing processes.

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are specifically engineered to address common challenges in sheet metal assembly, such as material fatigue and corrosion. Made from 18-8 stainless steel, they offer excellent resistance to rust and oxidation, which is critical in outdoor or high-moisture environments. The flat head design with an 82° countersink angle ensures a secure, flush fit, reducing the risk of protrusion and improving aerodynamic or aesthetic surfaces. By utilizing a thread forming tapping method, these screws eliminate the need for separate tapping operations, saving time and reducing tooling costs. Their fully threaded and pointed tip allows for quick penetration and strong retention in materials up to 0.025" thick, making them ideal for HVAC, automotive, and electronics enclosures where durability and precision are paramount.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 10 screw size, 12 threads per inch, and 1-1/4" length, ensuring precise fit in sheet metal applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances. The screw features a square drive (No. 2 size) for secure installation and is designed for use with a No. 21 drill bit (0.159" diameter), supporting consistent performance in industrial settings.
