S-90286A151 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with a 1/4" external hex drive for secure installation and reduced tool slippage
• Enhanced load distribution from the 0.328" flange, minimizing material stress and preventing pull-through in sheet metal
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly steps
• Full threading and pointed tip ensure quick starts and consistent engagement along the entire 3/4" length for reliable fastening
• Precision sizing with No. 6-18 thread specification and compatibility with No. 32 drill bits for accurate fit in 0.025" maximum thickness materials
• Compliance assurance with RoHS 3 and REACH regulations, guaranteeing safe use in industrial environments
• Right-hand threading provides standard, intuitive installation for efficient high-volume assembly operations

Professional Applications & Engineering Value

This hex head tapping screw delivers exceptional value in sheet metal applications where vibration resistance and joint integrity are critical. The thread forming design displaces material rather than removing it, creating stronger threads with improved fatigue resistance compared to thread-cutting alternatives. The combination of fully threaded construction and pointed tip enables rapid penetration and maximum thread engagement in thin gauge materials up to 0.025" thickness. The external hex drive accommodates high torque applications while the integrated flange provides wider bearing surface, distributing clamp load effectively to prevent sheet deformation. These engineering features make this No. 6-18 sheet metal screw ideal for HVAC systems, electronic enclosures, automotive panels, and industrial equipment where reliable fastening in thin materials is essential.
