S-93406A317 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Enhanced load distribution from the wide truss head design, reducing the risk of material pull-through in thin sheet metal.
• Efficient, secure installation using the No. 3 Phillips drive, providing a positive grip and minimizing cam-out during driving.
• Strong, reliable thread forming with A/AB type tapping, creating durable threads without chips in sheet metal up to 0.025" thickness.
• Full-length threading ensures maximum grip and holding power along the entire 1-1/4" length for secure assemblies.
• Environmental compliance with RoHS 3 and REACH standards, ensuring safe, sustainable use in regulated industries.
• Precision fit with 0.242" thread diameter and 10 threads per inch, delivering consistent performance in pre-drilled 5.5mm holes.

Professional Applications & Engineering Value

These No. 14 Phillips Truss Head Tapping Screws are engineered to address common challenges in sheet metal fabrication, such as material stripping and corrosion. The 18-8 stainless steel provides excellent resistance to rust and oxidation, extending service life in demanding conditions. The thread forming design displaces material to create strong, clean threads without generating chips, preventing contamination and ensuring a tight fit. The wide truss head offers a larger bearing surface, distributing clamp load effectively to prevent deformation in thin-gauge metals. This makes them ideal for HVAC, electronics enclosures, and automotive assemblies where vibration resistance and durability are critical. Their compatibility with a standard 5.5mm drill bit simplifies installation, reducing labor time and improving efficiency in high-volume production environments.

Specification Summary & Compliance

This screw features a No. 14 size with a 0.242" thread diameter and 10 threads per inch, fully threaded for consistent engagement. It adheres to standard inch measurements and is designed for use with a No. 3 Phillips drive. The thread forming (Type A/AB) tapping method ensures precise thread creation in sheet metal. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming it is free of restricted substances and suitable for environmentally conscious applications.
