S-92400A520 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastics through advanced Tri-Lobe shank design that creates strong, permanent threads without material cracking
• Excellent corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in demanding environments
• Optimized installation efficiency with external hex drive design providing secure tool engagement and high torque transmission
• Reduced assembly stress through thread forming technology that displaces material rather than removing it, maintaining plastic integrity
• Precise fit and compatibility with No. 29 drill bit (0.136") for consistent performance across plastic applications
• Enhanced flange stability with 0.348" diameter providing superior load distribution and preventing pull-through
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

This TRS thread forming screw delivers exceptional engineering value in plastic assembly applications where material integrity and long-term performance are critical. The Tri-Lobe shank cross-section and thread forming technology work synergistically to create strong, reliable threads in plastic substrates without generating chips or compromising material structure. Made from 18-8 Stainless Steel, this fastener provides excellent corrosion resistance while the external hex drive ensures secure tool engagement during high-volume installation. The combination of 16 threads per inch and blunt tip design allows for smooth thread formation while minimizing stress concentration points that can lead to plastic cracking. These plastic fasteners are particularly valuable in automotive components, electronic enclosures, and consumer products where vibration resistance and material compatibility are essential.

Specification Summary & Compliance

This No. 8 x 1" thread forming screw features precision 0.164" thread diameter with 16 TPI right-hand threading and fully threaded construction for maximum engagement. The 1/4" hex head width with 0.141" head height provides optimal tool clearance while the 0.348" flange diameter ensures proper load distribution. Manufactured to exacting standards with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, meeting international environmental and safety regulations for industrial use.
