S-94077A414 3/8"-16 x 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with specialized coating extends service life in demanding industrial environments
• Enhanced torque transmission through external hex drive design prevents stripping during high-torque installation
• Secure fastening in steel and sheet metal with thread-forming technology that creates strong, permanent threads without chips
• Increased stability and load distribution from integrated flange design eliminates need for separate washers
• Improved anti-tampering security with five-lobe shank cross-section that resists unauthorized removal
• Reliable coarse threading with UNC standard ensures quick installation and strong holding power in various materials
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These thread forming tapping screws are engineered specifically for challenging steel and sheet metal applications where vibration resistance and long-term reliability are critical. The Ultra-Corrosion-Resistant coated steel construction prevents rust and degradation in harsh environments, while the five-lobe shank design provides superior resistance to loosening under dynamic loads. The flanged hex head combines easy installation with enhanced clamping force, distributing pressure evenly across joined surfaces. With 3/8"-16 UNC coarse threading and partial threading configuration, these screws deliver optimal performance in structural assemblies, electrical enclosures, and industrial equipment where thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs.

Specification Summary & Compliance

These 3/8"-16 UNC thread forming screws feature Class 2A thread tolerances with coarse thread spacing, manufactured to industry standards for consistent performance. The partially threaded design provides 2½" minimum thread length on a 3" overall length, complemented by a 0.78" flange diameter for optimal load distribution. Engineered for use with 11/32" drill bits (0.3437" diameter), these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe industrial application across global markets.
