S-90065A316 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments.
• Efficient thread forming creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor.
• Flush mounting capability with standard 82° flat head profile and full countersinking for smooth, snag-free surfaces.
• High drive torque transmission through No. 3 Phillips drive, minimizing cam-out and ensuring secure fastening.
• Full-length threading provides maximum grip and holding power across the entire 1-1/4" length in sheet metal applications.
• Environmental compliance with RoHS 3 and REACH regulations ensures safe use in regulated industries and applications.
• Precision sizing with No. 14 diameter and 10 threads per inch delivers reliable, consistent performance in standardized assemblies.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design (Type A) eliminates the need for separate tapping operations, reducing assembly time and costs while creating strong, strip-resistant threads in metal substrates. The fully threaded configuration ensures maximum engagement and pull-out resistance, critical in vibration-prone environments. With an 82° countersink angle and flat head profile, these screws sit flush with surfaces, preventing interference in tight spaces. The Phillips drive system provides reliable torque transmission during installation, making them ideal for high-volume manufacturing, HVAC systems, electrical enclosures, and metal fabrication where durability and compliance with environmental standards are essential.

Specification Summary & Compliance

These No. 14 Phillips flat head tapping screws feature a 0.242" thread diameter with 10 threads per inch and standard inch measurements. The Type A thread forming method follows industry standards for sheet metal fastening, requiring a 5.5 mm (0.2165") drill bit for proper installation. The screws maintain precise dimensional tolerances suitable for industrial applications and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability.
