• Reliable performance in thin materials with a maximum drilling thickness of 0.025", making them perfect for precision sheet metal work.
• Full-length threading ensures maximum grip and holding power along the entire 3" length for secure, long-lasting assemblies.
• Environmental and safety compliance with RoHS 3 and REACH regulations, ensuring safe use in various markets and applications.

Professional Applications & Engineering Value

These No. 14 flat head tapping screws are engineered specifically for demanding sheet metal applications, where material integrity and fastener reliability are critical. The 18-8 stainless steel provides excellent resistance to rust and corrosion, extending service life in environments exposed to moisture or chemicals. The thread forming (Type A/AB) design displaces material to create strong, precise internal threads without generating chips, eliminating the risk of contamination in electrical enclosures, HVAC systems, and automotive panels. The square drive offers superior torque transmission compared to Phillips, reducing strip-out and improving assembly efficiency. With a 0.242" thread diameter and 10 threads per inch, these screws deliver optimal clamping force and are compatible with standard 5.5mm drill bits, streamlining the installation process for professionals.

Specification Summary & Compliance

This product features a right-hand thread, fully threaded shank, and standard flat head profile with an 82° countersink angle. The thread diameter is 0.242" with approximately 10 threads per inch, adhering to common inch-series standards for tapping screws. Manufacturing and material compliance include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring they are free of restricted hazardous substances and safe for industrial use.
