S-92400A210 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in industrial environments
• Enhanced holding power in plastic materials through advanced Tri-Lobe shank design that displaces material without creating chips
• Maximum torque transmission with external hex drive design for secure installation and reduced tool slippage
• Efficient thread forming action that creates strong, permanent threads in plastic substrates without pre-tapping
• Optimized plastic fastening performance with blunt tip design that prevents material splitting during installation
• Reliable flange diameter (0.348") provides improved load distribution and prevents pull-through in softer materials
• Full threading coverage ensures consistent clamping force along the entire fastener length

Professional Applications & Engineering Value

This No. 8-16 TRS thread forming screw delivers exceptional engineering value for plastic assembly applications where traditional fasteners fail. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength. The innovative Tri-Lobe shank cross-section revolutionizes plastic fastening by displacing material radially, creating zero clearance threads that significantly outperform standard machine screws. This design eliminates the common problem of stripped threads in plastic components, ensuring reliable long-term performance in automotive trim, electronic enclosures, and consumer products. The external hex drive allows for high torque application without cam-out issues, while the fully threaded blunt tip prevents material cracking during installation - a critical advantage when working with brittle plastics.

Specification Summary & Compliance

This thread forming screw features precise No. 8-16 thread specifications with 0.164" thread diameter and 16 TPI (threads per inch) for consistent performance. Manufactured to exacting standards with Class 2A thread tolerances, the fastener is designed for use with No. 29 drill bit (0.136" diameter) in plastic applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use across global markets.
