S-90380A377 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention through thread forming technology that creates strong, vibration-resistant connections without requiring pre-tapped holes
• Enhanced corrosion resistance with zinc plating that protects against environmental elements in industrial settings
• Optimized drive efficiency with Phillips No. 2 drive that provides reliable torque transmission and prevents cam-out during installation
• Complete thread engagement with fully threaded design that maximizes holding power across the entire fastener length
• Safe material penetration featuring a blunt tip that minimizes plastic cracking or stress concentration during installation
• Streamlined installation process with precise 3mm drill bit compatibility that eliminates guesswork and ensures proper fit
• Pan head design advantage offering a rounded profile with good bearing surface for secure fastening in plastic assemblies

Professional Applications & Engineering Value

This M4 x 12mm zinc-plated steel TRS tapping screw delivers exceptional engineering value for plastic assembly applications where traditional fastening methods fall short. The thread forming technology creates precise mating threads in plastic materials through cold flow rather than cutting, eliminating chip formation and resulting in stronger, more reliable connections. The zinc-plated steel construction provides the necessary durability for industrial environments while preventing galvanic corrosion when used with various plastic types. With its Phillips drive and standardized pan head design, this fastener enables efficient assembly line operations while maintaining consistent clamping force. The fully threaded configuration ensures maximum engagement in plastic components, making it ideal for electronics enclosures, automotive trim, consumer products, and industrial equipment where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This metric M4 tapping screw features a 12mm length with 1.79mm thread pitch and standard pan head profile (7mm diameter, 2.8mm height). Manufactured to TRS (Thread Rolling Screw) specifications for thread forming applications in plastics, it ensures precise fit with 3mm drill bit preparation. The fastener maintains dimensional accuracy suitable for industrial plastic assembly requirements. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for global industrial applications.
