S-90380A287 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Exceptional holding power in plastic materials through advanced TRS thread forming technology that creates secure, permanent threads
• Reduced installation torque and material stress with tri-lobe shank design that displaces material efficiently during driving
• Precise Phillips No. 2 drive compatibility ensures secure tool engagement and prevents cam-out during installation
• Optimized for plastic assembly with blunt tip design that prevents material cracking and ensures proper thread starting
• Full-length threading provides maximum engagement depth and consistent clamping force along the entire fastener length
• Industry compliance assurance with RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

This zinc-plated steel TRS tapping screw is specifically engineered for plastic fastening applications where reliability and material integrity are paramount. The thread forming technology creates strong, permanent threads in plastic substrates without generating chips, eliminating contamination concerns in sensitive assemblies. The tri-lobe shank cross-section reduces installation torque by up to 30% compared to standard fasteners, minimizing the risk of plastic material stress cracking during assembly. With its Phillips drive No. 2 configuration and 7/8" length, this fastener delivers optimal performance in electronic enclosures, automotive plastic components, and consumer product assemblies where vibration resistance and long-term holding power are critical engineering requirements.
