S-90286A317 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior sheet metal grip with thread forming design prevents material stripping and ensures reliable, vibration-resistant connections
• Enhanced installation efficiency through combined external hex/slotted drive for versatile tool compatibility and quick fastening
• Increased load distribution from the integrated 0.52" flange, reducing surface pressure and preventing material deformation
• Full-length threading provides maximum engagement along the entire 1-1/2" length for superior pull-out resistance in thin materials
• Precision compatibility with standard 5.5mm (0.2165") drill bits and 0.025" maximum drilling thickness for consistent performance
• Environmental compliance assurance with RoHS 3 and REACH regulations, meeting international environmental standards
• Durable construction featuring pointed tip for easy starting and 3/8" hex head for secure tool engagement during high-torque applications

Professional Applications & Engineering Value

These No. 14 thread forming tapping screws deliver exceptional engineering value in sheet metal assembly applications where material integrity is critical. The thread forming tapping method creates precise mating threads without generating chips, eliminating contamination risks in sensitive electrical or ventilation systems. The flanged hex head design combines the installation convenience of external drive systems with the bearing surface advantages of washers, reducing assembly time while providing superior clamp force distribution. With 10 TPI threading and 0.242" diameter, these screws maintain excellent engagement in thin-gauge materials up to 0.025" thickness, preventing strip-out in repetitive disassembly scenarios common in maintenance applications.

Specification Summary & Compliance

This thread forming tapping screw features No. 14 size with 10 threads per inch and right-hand threading direction. The fully threaded 1-1/2" length provides complete engagement, while the 0.52" flange diameter offers enhanced load distribution. Manufactured to Tapping Screw Type A specifications with pointed tip for easy starting. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in various industrial applications.
