• Maximum thread engagement through fully threaded design, delivering superior holding power across the entire 1-3/4" length
• Precision compatibility with 0.2165" (5.5 mm) drill bits, ensuring accurate hole preparation and secure fastening in sheet metal up to 0.025" thickness
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing and global market acceptance

Professional Applications & Engineering Value

These No. 14 Phillips flat head tapping screws are specifically engineered for demanding sheet metal applications where reliability and efficiency are paramount. The thread forming technology eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The zinc-plated steel construction provides essential corrosion protection in industrial environments, while the 82° countersink angle ensures flush mounting for smooth surfaces in HVAC systems, electrical enclosures, and metal fabrication projects. The fully threaded design maximizes pull-out resistance, making these A/AB type tapping screws ideal for securing thin gauge materials where joint integrity is critical.

Specification Summary & Compliance

These thread forming screws feature precision right-hand threads with standard inch measurements: No. 14 thread diameter (0.242"), 10 threads per inch, and 1-3/4" length. The flat head design includes 0.462" head diameter and 0.148" head height with standard profile. Manufactured to industry standards for sheet metal fastening, these screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial applications.
