S-94077A105 3/8"-16 x 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with specialized coating extends service life in harsh industrial environments
• Enhanced driving torque transmission through external hex head design prevents stripping during installation
• Secure flanged seating distributes clamping force evenly without requiring separate washers
• Optimized thread forming action with five-lobe shank creates strong, permanent threads in steel and sheet metal
• Reliable coarse UNC threading provides excellent pull-out resistance in various material thicknesses
• Full threading along 1-1/2" length ensures maximum engagement and holding power
• Environmental compliance assurance with RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These 3/8"-16 UNC thread forming screws deliver exceptional performance in demanding 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 industrial environments, while the five-lobe shank design displaces material during installation to create secure, permanent threads without chips or debris. The flanged hex head configuration combines easy installation with distributed bearing pressure, eliminating the need for additional washers and reducing assembly time. Engineered for heavy-duty construction and manufacturing applications, these tapping screws maintain structural integrity under constant stress and environmental exposure.

Specification Summary & Compliance

Manufactured to precise UNC coarse thread standards with 3/8"-16 threading and Class 2A tolerance for consistent performance. Features fully threaded design with 1-1/2" length and blunt tip for controlled penetration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications. The external hex drive and flanged head provide reliable installation and secure fastening in steel and sheet metal substrates.
