S-93406A318 Length 1 1/2" 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.
• Enhanced load distribution from the wide truss head design, reducing material stress and preventing pull-through in sheet metal applications.
• Eliminates pre-tapping requirements through thread forming technology, saving installation time and labor costs.
• Secure, non-slip driving with the No. 3 Phillips drive, providing consistent torque transfer and reducing tool slippage.
• Full-length threading for maximum grip along the entire 1-1/2" length, ensuring superior holding power in assemblies.
• Compliance with environmental regulations including RoHS 3 and REACH, making them suitable for global industrial supply chains.
• Optimized for 0.025" maximum thickness sheet metal with precise 5.5mm drill bit compatibility, ensuring clean installations.

Professional Applications & Engineering Value

These thread forming tapping screws are engineered specifically for sheet metal fastening challenges where traditional fasteners fail. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, crucial for outdoor equipment, HVAC systems, and electronic enclosures. The Phillips truss head design offers a larger bearing surface, distributing clamp load effectively to prevent sheet metal deformation—a common issue in thin-gauge applications. With their A/AB thread type and right-hand threading, they create strong, permanent threads in pre-drilled holes without requiring tapped threads, significantly reducing assembly time and tooling costs. The fully threaded shank ensures consistent engagement across the entire material thickness, providing reliable performance in vibration-prone environments.

Specification Summary & Compliance

This No. 14 sheet metal screw features a 0.242" thread diameter with 10 threads per inch and 1-1/2" length, manufactured to precise dimensional standards for consistent performance. The thread forming tapping method creates secure fastening without pre-tapped holes. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial applications worldwide.
