S-90286A201 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power with flanged design that distributes load evenly and prevents pull-through in thin sheet metal applications
• Efficient thread forming technology creates precise mating threads without chips, eliminating debris contamination in sensitive assemblies
• External hex/slotted drive compatibility provides versatile installation options for both manual and power tools in various industrial settings
• Full threading with pointed tip ensures rapid engagement and consistent fastening depth across the entire 1-1/4" length
• Optimized No. 8-15 thread configuration delivers excellent tensile strength and vibration resistance in sheet metal joints
• Environmental compliance assurance with RoHS 3 and REACH compliance for use in regulated industries and global supply chains
• Precision-matched drilling compatibility with No. 29 drill bit (0.136" diameter) for clean, accurate hole preparation up to 0.025" thickness

Professional Applications & Engineering Value

These hex head sheet metal tapping screws are engineered specifically for thread forming applications where traditional cutting screws may compromise material integrity. The No. 8-15 thread configuration with 0.164" diameter provides optimal balance between engagement strength and material displacement, making them ideal for sheet metal assemblies in HVAC systems, electronic enclosures, and automotive components. The fully threaded design with pointed tip ensures immediate engagement without pilot hole tapping, while the flanged head creates a secure bearing surface that eliminates the need for separate washers. This combination addresses common industrial challenges including vibration loosening, material fatigue, and installation efficiency in high-volume production environments.

Specification Summary & Compliance

This No. 8-15 x 1-1/4" sheet metal tapping screw features standard right-hand threads with 15 threads per inch precision and fully threaded configuration. The external hex/slotted drive accommodates standard industrial tools, while the 0.348" flange diameter provides enhanced clamping surface. Manufactured to industry standards for thread forming Type A tapping screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
