S-94077A416 3/8"-16 x 5" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with ultra-corrosion-resistant coated steel construction for long-lasting performance in harsh industrial environments
• Maximum holding power through advanced thread forming technology that creates stronger, more secure connections in steel and sheet metal
• Enhanced torque transmission with external hex drive and five-lobe shank design preventing cam-out during installation
• Flanged head design eliminates the need for separate washers while providing superior load distribution
• Coarse UNC threading ensures faster installation and reliable performance in demanding applications
• Extended service life with partial threading that maintains structural integrity while reducing material stress
• Regulatory compliance meets RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These 3/8"-16 UNC tapping screws are engineered specifically for steel and sheet metal applications where vibration resistance and long-term reliability are critical. The ultra-corrosion-resistant coated steel construction prevents degradation in industrial environments, while the thread forming technology creates stronger, more permanent connections by displacing material rather than removing it. The five-lobe shank design combined with external hex drive ensures maximum torque transmission without stripping, making them ideal for high-stress assemblies. The flanged head provides excellent bearing surface, eliminating the need for additional washers and reducing installation time. These features collectively address common industrial challenges including joint failure, corrosion-induced weakening, and installation inefficiencies in metal fabrication and structural applications.

Specification Summary & Compliance

These tapping screws feature UNC coarse threading with standard Class 2A thread tolerances, ensuring consistent performance across industrial applications. The 3/8"-16 thread size with partial threading and 5-inch length provides optimal engagement for various material thicknesses. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental responsibility and safety compliance. The thread forming design follows industry standards for Type C tapping screws, delivering reliable performance in steel and sheet metal assemblies without requiring pre-tapped holes.
